Photosynthesis is the process by which plants, algae, and cyanobacteria use sunlight, carbon dioxide, and water to produce oxygen and energy in the form of glucose. It occurs in two stages - the light reaction phase which is dependent on light, and the dark phase or Calvin cycle which is light independent. The main pigments used in photosynthesis are chlorophyll a and b, which absorb light and reflect green light, giving leaves their green color, and carotenoids which also absorb light. Photosynthesis provides nutrients and oxygen for other organisms.

This document discusses food webs and trophic dynamics in marine ecosystems. It explains that photosynthesis by primary producers like phytoplankton converts sunlight into organic compounds, which are then consumed by herbivores. Higher trophic levels like carnivores consume herbivores or other carnivores. Decomposers like bacteria break down organic matter and release nutrients to be recycled. Energy is lost at each trophic level, so biomass decreases with increasing trophic level despite larger organism size. Food chains transfer energy between trophic levels in the grazing and detritus food chains.Sulfur cycle PERIOD 4

The sulfur cycle describes the movement of sulfur through the environment. Sulfur is abundant in the Earth's crust and is essential for proteins and vitamins in organisms. It cycles between the atmosphere, terrestrial environments, and freshwater reservoirs. Human activities like burning fossil fuels and industrial pollution are releasing excess sulfur into the air, causing problems like acid rain which damages ecosystems. Reducing the use of fossil fuels would help limit acid rain and its negative impacts on the environment.Use of Algae for waste water treatment

Biogeochemical cycles describe the cycling of essential nutrients like carbon, oxygen, nitrogen, phosphorus, and sulfur between the biotic (living) and abiotic (non-living) components of ecosystems. Energy from the sun drives these cycles as nutrients are exchanged between organisms, water, air, soil, and rock. Humans have disrupted natural biogeochemical cycles through activities like burning fossil fuels, clearing vegetation, using fertilizers, and pollution, which has contributed to issues like climate change and algal blooms.Functions of Carbon, Hydrogen and Oxygen

Carbon, hydrogen, and oxygen are the three most abundant elements in plants, comprising 95% of their dry weight. They are key components of organic compounds and provide structure to plants. Carbon and hydrogen are absorbed from air and water, while oxygen is partly taken from air and water. Nitrogen is also important, typically comprising 1-5% of dry weight in plants. Nitrogen can be taken up by plants as nitrate or ammonium ions and is required for photosynthesis, growth, and metabolism. The document discusses the various forms and sources of nitrogen in soil as well as gains and losses of nitrogen in soil systems.FINAL PROJECT REPORT

The nitrogen cycle describes the movement of nitrogen through the environment. Nitrogen exists in the atmosphere but is not directly usable by plants and animals. It is converted to usable forms through nitrogen fixation by lightning and bacteria. Nitrogen-fixing bacteria convert nitrogen gas into ammonia, which plants can use, and nitrifying bacteria further convert ammonia into nitrites and nitrates. Denitrifying bacteria convert nitrates back to nitrogen gas, which returns to the atmosphere. Human activities like fossil fuel combustion and excessive fertilizer use have disrupted the nitrogen cycle.Soils 509 lecture no. 11 12 13_14 soil and water pollution

Water pollution has become one of the most serious
problems of todays civilization. In the last few years
considerable amount of research has been done on the
potential of aquatic macrophytes for pollutant removal or even
as bio-indicators for heavy metals in aquatic ecosystems. Water
hyacinth is one of the aquatic plant species successfully used
for wastewater treatment. It is very efficient in removing
pollutants like suspended solids, BOD, organic matter, heavy
metals and pathogens. This paper mainly focuses on the
treatment of waste water using the plant water hyacinth and
has given emphasis to the removal of heavy metals by the
plant. Water hyacinth could grow in sewage; they absorb and
digest the pollutants in wastewater, thus converting sewage
effluents to relatively clean water. Thus, the plants hold
promise as a natural water purification system, which could
be established at a fraction of the cost of a conventional sewage
treatment facility. The study conducted in this regard revealed
how efficiently wastewater could be treated using the plant

The document discusses ecosystems and trophic levels. It explains that there are four trophic levels: primary producers (plants), primary consumers (herbivores), secondary consumers (carnivores), and decomposers. Between each trophic level, about 10% of energy is transferred. Nutrients cycle through ecosystems with the help of decomposers, which break down organic material and release nutrients back into the soil. The document also discusses nutrient pollution in coastal waters, noting that excess nitrogen and phosphorus can lead to eutrophication and decreased biodiversity.Project ecosystem - FRESH WATER ECOSYSTEM

North Korea experienced a food crisis after losing support from the Soviet Union, which had previously provided chemicals and petroleum needed for agriculture. Without these imports, North Korea could no longer produce sufficient fertilizer, which is essential for supplying nitrogen and other nutrients to crops. Nitrogen is the nutrient most often limiting for plant growth, and industrial fertilizer production requires significant energy from petroleum. As a result, North Korea's farming system failed due to the lack of fertilizer inputs, leading the country to experience widespread starvation.Ecological cycles

Photosynthesis is a fundamental biological process that enables plants, algae, and some bacteria to convert light energy from the sun into chemical energy in the form of glucose, which fuels their growth and development. This process occurs primarily in the chloroplasts of plant cells, where chlorophyll, the green pigment, captures sunlight. The basic equation for photosynthesis can be simplified as carbon dioxide (CO) and water (HO), in the presence of light energy, yielding glucose (CHO) and oxygen (O).
The process can be divided into two main stages: the light-dependent reactions and the light-independent reactions (or Calvin cycle). In the light-dependent reactions, which occur in the thylakoid membranes of the chloroplasts, sunlight is absorbed by chlorophyll and used to split water molecules, releasing oxygen as a byproduct. This phase also generates the energy carriers ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are essential for the next stage.
In the Calvin cycle, which takes place in the stroma of the chloroplasts, the ATP and NADPH produced in the light-dependent reactions are used to convert carbon dioxide from the atmosphere into glucose. This process involves a series of chemical reactions, starting with the fixation of carbon dioxide by the enzyme RuBisCO, forming a three-carbon compound. Through a series of transformations, these carbon compounds are eventually converted into glucose, which the plant can use for energy or store for later use.
Photosynthesis is not only crucial for the survival of plants but also for life on Earth. The oxygen released during the process is essential for the respiration of most living organisms. Additionally, photosynthesis forms the base of the food chain, providing the energy that fuels all life forms. Plants use the glucose produced to grow, develop, and reproduce, and this stored energy is passed on to herbivores and subsequently to carnivores in a cascading flow of energy through ecosystems.
Beyond its role in energy production and oxygen release, photosynthesis has a profound impact on global carbon cycles. By absorbing carbon dioxide from the atmosphere, plants help mitigate the effects of climate change. Forests, grasslands, and other plant ecosystems act as carbon sinks, storing carbon that would otherwise contribute to the greenhouse effect.
In summary, photosynthesis is an elegant and efficient process that sustains life on Earth by converting solar energy into a usable form for living organisms, producing oxygen, and regulating atmospheric carbon levels. Understanding this process not only highlights the importance of plants in our ecosystems but also emphasizes the delicate balance of natural processes that sustain the planet.Photosynthesis in bacteria and its types

The document discusses photosynthesis and the key pigments and structures involved. It explains that:
- Photosynthesis occurs in the chloroplasts of plants, which contain chlorophyll, the pigment that absorbs light energy essential for photosynthesis.
- The two main stages of photosynthesis are the light-dependent reactions, where light energy is captured to make ATP and NADPH using water as the electron donor, and the light-independent reactions where CO2 is fixed into sugars using the ATP and NADPH produced.
- The main photosynthetic pigments are chlorophyll a and b as well as carotenoids, and each absorbs different wavelengths of light with peaks in the blue and red regionschapter7photo1kmkt-160607004122.pdf

The document summarizes key aspects of photosynthesis, including:
- Photosynthesis occurs in chloroplasts within plant cells and involves the absorption of light energy by chlorophyll to convert carbon dioxide and water into glucose and oxygen.
- Chlorophyll is the primary photosynthetic pigment that absorbs light in the blue and red wavelengths while reflecting green light, giving plants their green color.
- Other pigments like carotenoids help capture a broader range of wavelengths and transfer energy to chlorophyll.
- The light-dependent and light-independent reactions of photosynthesis utilize the energy from light absorption to fix carbon into sugars.Photosynthesis ppt

Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of glucose. It occurs in two stages - the light-dependent reaction where sunlight is absorbed to make ATP and NADPH, and the light-independent reaction where carbon dioxide is fixed using ATP and NADPH to make glucose. Photosynthesis takes place in chloroplasts within plant cells and is essential for life on Earth as it produces the oxygen needed for respiration and food in the form of glucose.photosynthesis.pptx

Plants prepare their food through the process of photosynthesis. Photosynthesis requires sunlight, water, carbon dioxide, and chlorophyll. The chapter discusses how plants use these factors - absorbing water through their roots and carbon dioxide from the air, while using chlorophyll and sunlight to produce food and release oxygen. A mind map and video are also used to illustrate the process of photosynthesis for the students.Nutrition

This document discusses different modes of nutrition in living organisms. It describes autotrophic nutrition, which occurs in organisms like plants that can synthesize their own food through photosynthesis or chemosynthesis. It also describes heterotrophic nutrition, where organisms obtain organic carbon from other living things. Heterotrophic nutrition includes saprophytic, parasitic, and holozoic (animal) modes. Photosynthesis uses carbon dioxide, water, and sunlight to produce oxygen and energy-rich organic compounds like carbohydrates. It takes place in chloroplasts in plant cells.Photosynthesis

Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce oxygen and energy in the form of glucose. It takes place in chloroplasts through the use of chlorophyll and other pigments and involves two stages - the light dependent reaction where ATP and NADPH are produced, and the light independent reaction where carbon is fixed into glucose. Oxygen is released as a byproduct of photosynthesis, which is essential for aerobic life on Earth.Photosynthesis

Green plants and other organisms perform photosynthesis, the process by which solar energy is converted into chemical energy and stored in organic molecules. During photosynthesis, carbon dioxide, water, and sunlight are used to produce glucose and oxygen. The two main stages are the light reaction phase, where light energy is absorbed and used to produce ATP and NADPH, and the Calvin cycle, where carbon dioxide is incorporated into organic compounds to form glucose. Chloroplasts in plant leaves contain chlorophyll which absorbs sunlight to drive photosynthesis, producing oxygen as a byproduct and fueling the biosynthesis of carbohydrates, proteins, and fats that sustain life on Earth.Botany ppt on plant physiology and metabolism

This document summarizes key information about photosynthesis. It discusses that photosynthesis captures light energy to convert carbon dioxide and water into glucose through chloroplasts in plant leaves. It describes the two stages of photosynthesis - the light-dependent reactions where ATP and NADPH are produced, and the Calvin cycle where glucose is produced. It also discusses C3, C4, and CAM pathways and how plants with different pathways may be impacted by increasing carbon dioxide levels. Potential targets for improving plant photosynthesis through genetic engineering or other methods are also outlined.Photosynthesis
- 1. PHOTOSYNTHESIS UNIT-6
- 2. WHAT IS PHOTOSYNTHESIS? The process that occurs in green plants, whereby solar energy is converted into chemical energy and stored as organic molecules by making use of carbon dioxide, sunlight and water. WHO OR WHAT CAN PHOTOSYNTHSIZE? 1. Photoautotrophs can photosynthesize. 2. Include: green plants, algae, cyanobacteria and green protists
- 3. RAW MATERIALS OF PHOTOSYTHESIS? Carbon dioxide, Sunlight and Water. WHY DO PLANTS PHOTOSYNTHESIS? To provide nutrients and oxygen for heterotrophs are dependents, because they cannot produce there own food.
