Plants perform photosynthesis, a chemical reaction that occurs in chloroplasts and uses chlorophyll to produce glucose and oxygen from carbon dioxide, water, and light energy. Photosynthesis takes place in plant leaves, where carbon dioxide enters and oxygen exits through small openings, while water and minerals are absorbed by the roots. The glucose produced is used by the plant for energy and building new tissues, or is released through respiration.

This document discusses the differences between substances, mixtures, and compounds. It defines a substance as matter made of the same atoms, and notes that elements and compounds are types of substances. A mixture is two or more substances physically blended but not chemically bonded. Granite and air are given as examples of heterogeneous and homogeneous mixtures respectively. The document explains that mixtures can be separated into their original substances using physical means, while compounds require chemical changes to separate them into their component elements.Interactions:Transfer of Energy in Trophic Levels, Prepared by: Edsyl Berongo...

This document discusses trophic levels and energy transfer through food chains and webs. It begins by stating the lesson objectives of describing energy transfer through trophic levels, distinguishing between producers and consumers, and constructing a food chain. It then defines producers as organisms that convert sunlight to chemical energy, consumers as organisms that obtain energy by eating producers or other consumers, and decomposers as organisms that break down dead organisms. The document explains that food chains show a linear transfer of energy from producers to consumers to decomposers, while food webs illustrate a more complex web of interconnected food chains in an ecosystem. Students are assigned to answer questions about food webs versus food chains and construct their own food web.Bio-diversity grade 9.pptx

The document summarizes the respiratory and circulatory systems. It discusses the major organs involved in breathing including the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles and lungs. It explains that during inhalation, air is brought into the lungs through the nose and mouth and passes through the pharynx, larynx, trachea and bronchi before reaching the bronchioles and alveoli in the lungs where oxygen passes into the blood and carbon dioxide passes out of the blood. During exhalation, the process is reversed as carbon dioxide is expelled from the lungs.COLORS OF LIGHT.pptx GRADE 8 SCIENCE (quarter1)

The document discusses the colors of light and the visible spectrum. It explains that:
- The visible spectrum is part of the electromagnetic spectrum and includes the colors red, orange, yellow, green, blue, indigo, and violet. Each color has a different wavelength, with red having the longest wavelength and violet having the shortest.
- When white light passes through a prism, the different wavelengths of light are refracted by different amounts due to differences in speed. This separates the light into the colors of the visible spectrum.
- Violet light has the highest frequency and energy of the colors, while red has the lowest frequency and energy. The ordering of colors from high to low energy is violetTypes of charging process

Electrons, protons, and neutrons are the main subatomic particles that make up atoms. Electrons have a negative charge and orbit the nucleus, while protons have a positive charge in the nucleus. Neutrons have no charge. Atoms consist of a nucleus surrounded by electrons. When an object gains or loses electrons through friction or contact with another object, it becomes positively or negatively charged respectively, as gaining or losing electrons leaves the object with an excess or deficit of protons. Charging by contact occurs when a charged object transfers charge to a neutral object they touch.Colors of light (Grade 8)

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. It occurs in chloroplasts in the leaves of plants. Plants need sunlight, water, and carbon dioxide to photosynthesize. The process converts these inputs into glucose and oxygen through a series of chemical reactions. Glucose is the food for the plant and can be used immediately, stored as starch, or converted into other compounds to help the plant grow.More Related Content

Plants use the process of photosynthesis to convert carbon dioxide, water, and sunlight into energy in the form of sugars that the plant can use to grow. Photosynthesis requires chlorophyll to trap sunlight, carbon dioxide from the air, water absorbed through the roots, and sunlight, which the plant's cells use to produce sugars to fuel growth. This process is essential for plants to produce their own food and obtain the energy needed to live and grow.Nutrition in plants

Here are the key points about homeostasis:
- Homeostasis refers to maintaining stable internal conditions in the body despite external changes.
- Conditions like temperature, water level, blood sugar, pH, and carbon dioxide levels are maintained within narrow ranges.
- Hormones help regulate these conditions and bring them back to normal levels when needed. Hormones are released from glands and travel through the bloodstream to target organs.
- For example, insulin and glucagon work together to maintain normal blood sugar levels. When blood sugar is too high, the pancreas releases insulin to lower it. When blood sugar is too low, the pancreas releases glucagon to raise it.

Photosynthesis is the process by which plants produce food from sunlight, carbon dioxide, and water. It occurs in the chloroplasts of green leaves and other green parts of plants. During photosynthesis, chlorophyll traps energy from sunlight which is used to convert carbon dioxide and water into oxygen and energy-rich food molecules like glucose. The food is then transported throughout the plant via phloem vessels, while water and minerals are absorbed from the soil and transported via xylem vessels to the leaves. Oxygen is released as a byproduct of photosynthesis.photosynthesis and respiration

Photosynthesis is the process by which plants capture light energy from the sun to convert carbon dioxide and water into glucose and oxygen. The chloroplasts in leaves contain chlorophyll which absorbs sunlight to drive the photosynthesis reaction. Carbon dioxide enters leaves through stomata and water is absorbed by roots. Oxygen is released as a byproduct through the stomata. Glucose produced is used by the plant for energy and growth or is stored as starch or oils. Respiration uses glucose and oxygen to produce energy for plant functions, releasing carbon dioxide and water.Photosynthesis 180903102548

This document discusses the modes of nutrition in plants. It explains that plants obtain nutrients through photosynthesis using chlorophyll, carbon dioxide, water and sunlight, or through heterotrophic nutrition by parasitizing other plants, decomposing dead matter, engaging in symbiotic relationships with algae, or trapping and digesting insects. The key modes of nutrition in plants are photosynthesis, parasitic relationships, saprophytism, symbiotic relationships, and insectivory.Plant physiology
Plant physiologyFauquier Horticulture
Ìý
The three main processes in plant physiology are photosynthesis, respiration, and transpiration. Photosynthesis allows plants to produce their own food (carbohydrates) from carbon dioxide, water, and sunlight using chlorophyll in their leaves. Respiration breaks down carbohydrates to release energy, which is used for growth and tissue building. Transpiration is the process by which plants lose water, primarily through their leaves, which serves purposes like mineral transport and cooling the plant.7 nutrition in plants

Plants are able to produce their own food through the process of photosynthesis, which occurs in their leaves. During photosynthesis, leaves use carbon dioxide, water, sunlight, and chlorophyll to produce carbohydrates from simple raw materials. This process allows plants to be autotrophic, unlike animals which must obtain food from other organisms. Photosynthesis is vital as it produces oxygen and feeds the rest of the world.Nutrition in plant 02

Chlorophyll in the leaves captures light energy which is used to convert carbon dioxide and water into glucose, the plant's food. Oxygen is released as a byproduct. Plants take in carbon dioxide through stomata in their leaves and water and minerals through their roots.GCSE Biology Revision

This document discusses different types of plant nutrition and classification. It begins by classifying plants based on their nutrition into heterotrophic, autotrophic, and saprophytic. It then describes each type in more detail. Autotrophic plants perform photosynthesis and obtain their energy from sunlight, while heterotrophic plants obtain nutrients by consuming other organisms or dead matter. Some examples of heterotrophic plants given are insectivorous and parasitic plants. The document also discusses symbiotic relationships between plants and bacteria that allow for biological nitrogen fixation.Plants and Photosynthesis
Plants and PhotosynthesisWills1cl

Plants are important for animal survival. They provide oxygen, food, medicine, fuel and other products. Plants and animals depend on each other - plants provide oxygen and animals provide carbon dioxide. Plants use chloroplasts and photosynthesis to produce their own food. Through photosynthesis, plants take in water and carbon dioxide and produce sugar and oxygen. Plants come in different shapes and sizes and can adapt to their environments.Food Production & The Environment

This document summarizes key processes in plant cells and how plants produce food. It discusses that plant cells contain organelles like the nucleus and chloroplasts which are not present in animal cells. Photosynthesis occurs in the chloroplasts and requires carbon dioxide, water, chlorophyll and sunlight to produce glucose and oxygen. The rate of photosynthesis is affected by the concentration of carbon dioxide, light intensity and temperature. Plants and animals are interdependent as plants produce oxygen for animals and animals produce the carbon dioxide needed for photosynthesis. The document also outlines how water and minerals are transported within plants and how transpiration occurs.Food Production & The Environment
