The document discusses how orchids and their velamen roots help protect the planet by absorbing atmospheric pollutants. The velamen is a spongy, multi-layered tissue that covers orchid roots and is capable of absorbing moisture, nutrients like carbon, nitrogen, and sulfur, and pollutants including carbon monoxide, carbon dioxide, methane, nitric oxide, and sulfur dioxide from the air. This allows orchids to grow in locations with improved exposure and reduced competition from other plants. Orchids also possess a CO2 concentrating mechanism that operates by reducing CO2 into carbohydrates at night and day, helping the plant more efficiently convert atmospheric carbon dioxide into carbohydrates through photosynthesis.

Carbon is one of the most important elements and is the main building block of organisms. It can be found in many everyday items and is readily available on Earth. Carbon dioxide in the air is used by plants through photosynthesis and enters animals when they eat food, then it is released back into the air through respiration. Fossil fuels are formed from decayed plants and animals over millions of years and release carbon dioxide when burned.Carbon Cycle

This document summarizes Crassulacean acid metabolism (CAM), a carbon fixation pathway used by some plants as an adaptation to arid conditions. CAM allows plants to collect carbon dioxide at night through open stomata and store it as an acid, then use the stored carbon dioxide for photosynthesis during the day when stomata are closed. This reduces water loss compared to C3 plants. Key benefits of CAM include keeping stomata closed during the day to reduce evapotranspiration and water loss. It was first observed in the Crassulaceae family.Photosynthesis3

The document discusses the carbon cycle and how carbon moves between organic and inorganic forms through photosynthesis and cellular respiration. It describes how producers convert carbon dioxide into organic compounds through photosynthesis, and how consumers and producers return carbon dioxide to the atmosphere through cellular respiration. It also discusses how carbon is absorbed by oceans and sediments, and incorporated into shells, coral, and limestone over long periods of time. The document then explains how humans disrupt the natural carbon cycle by burning fossil fuels, releasing carbon that has been fixed for thousands of years back into the atmosphere as carbon dioxide. This increased carbon dioxide is contributing to rising global temperatures and global warming.The Carbon Cycle by Tangstar Science

Cacti and bromeliads have developed several characteristics that allow them to survive in dry conditions through drought-tolerant mechanisms. Both are CAM plants that open their stomata at night to fix carbon. Cacti have lost their leaves and use their stems for photosynthesis, which are covered in a waxy cuticle and spines to reduce water loss. Their shallow roots spread widely to maximize water intake. Bromeliads form water-storing leaf tanks and have thick, water-storing leaves covered in scales. These adaptations allow cacti and bromeliads to effectively use water resources under drought conditions.Carbon cycle (1)

1) Photosynthesis requires light, carbon dioxide, and water. Plants have evolved leaf structures to supply these needs, including vascular bundles to transport water and sugars, and stomates for gas exchange.
2) When stomates close on hot or dry days to conserve water, it leads to build up of oxygen from light reactions and depletion of carbon dioxide for the Calvin cycle, causing inefficiency.
3) The enzyme RuBisCo can bind to either carbon dioxide or oxygen. Binding oxygen leads to photorespiration, which is inefficient and reduces carbon fixation. This provided selection pressure for C3, C4, and CAM photosynthesis adaptations.C4 photosynthesis

This document discusses C4 plants and their mechanism for carbon fixation. C4 plants have evolved a mechanism to fix carbon more efficiently than C3 plants in conditions like drought, heat, and low CO2/nitrogen levels. They concentrate CO2 around rubisco via a kranz anatomy structure to avoid photorespiration. The C4 mechanism involves converting phosphoenolpyruvate to oxaloacetate, then malate, transporting malate to bundle sheath cells where it is converted back to CO2 and pyruvate, regenerating phosphoenolpyruvate in a cyclic pathway.

C4Ìýcycle may also be referred as the di-carboxylic acid cycle or the β-carboxylation pathway or Hatch and Slack cycle or cooperative photosynthesis (Karpilov, 1970). For a long time, C3Ìýcycle was considered to be the only photosynthetic pathway for reduction of CO2Ìýinto carbohydrates. Kortschak, Hartt and Burr (1965) reported that rapidly photosynthesizing sugarcane leaves produced a 4-C compound like aspartic acid and malic acid as a result of CO2Ìý– fixation.
It was later supported by M. D. Hatch and C. R. Slack (1966) and they reported that a 4-C compound oxaloacetic acid (OAA) is the first stable product in CO2Ìýreduction process. This pathway was first reported in members of family Poaceae like sugarcane, maize, sorghum, etc. (tropical grasses), but later on the other subtropical plant like Atriplex spongiosa (Salt bush), Dititaria samguinolis, Cyperus rotundus, Amaranthus etc. So, the cycle has been reported not only in the members of Graminae but also among certain members of Cyperaceae and certain dicots.

This document summarizes the dark reaction (also known as the Calvin cycle) in plant photosynthesis. There are two major pathways for carbon fixation during this reaction: the C3 cycle and the C4 cycle. The C3 cycle fixes carbon dioxide into a 3-carbon compound called 3-phosphoglycerate using the enzyme rubisco. The fixed carbon is then reduced using ATP and NADPH to produce carbohydrates like glucose. The C4 cycle acts as an adaptation for plants in hot, dry environments. It initially fixes carbon dioxide into a 4-carbon compound in mesophyll cells before it is released and incorporated into the C3 cycle in bundle sheath cells.

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 occurs in two stages - the light reactions where light energy is captured to make ATP and NADPH using chlorophyll, and the carbon reactions where CO2 is fixed into sugars like glucose using ATP and NADPH in the Calvin cycle. Photosynthesis is vital as it provides oxygen and food, and consumes CO2. However, it is only 1-4% efficient in most plants due to photorespiration.

This document summarizes C3, C4, and CAM photosynthesis pathways. It explains that C3 photosynthesis involves carbon fixation using RUBISCO and the Calvin cycle. C4 and CAM pathways evolved to concentrate CO2 around RUBISCO to reduce oxygenation, which increases efficiency at high temperatures. C4 pathways use Kranz anatomy in leaf veins to separate processes. While more energy intensive, C4 and CAM avoid the carbon and energy losses of photorespiration seen in tropical C3 plants.C2 C3 C4 and CAM.pptx

- 10. CAM Plant Orchid To increase their intracellular CO2 concentration at the site of its fixation which allowed the primary Carboxylating enzyme rubisco to function more efficiently. The CO2 concentrating mechanism possessed by Orchids operates by sequentially Reducing CO2 into carbohydrates at two different times of day. The initial reduction of CO2 into a four-carbon sugar is done at night – when CAM plant stomata are open - by the enzyme PEP-carboxylase. Then, during the day when CAM plant stomata are closed, the four-carbon sugar is decarboxylated, increasing the plant's intercellular CO2 concentration, and the resulting CO2 is subsequently reduced back into a carbohydrate,
