C4 leaves are characterized by the presence of tightly packed, thick-walled bundle sheath cells all around the vascular bundle (Kranz anatomy). Study chloroplasts, the chemical equation, chlorophyll and the light and dark stages of photosynthesis. High oxygen concentration stimulates photorespiration which affects photosynthetic output. Chloroplasts Algae, protists … Answer: In dark reaction, phosphoglyceric acid forms phosphoglyceral dehyde by utilizing ATP molecules. Chlorophyta or Prasinophyta is a taxon of green algae informally called chlorophytes. Phosphoglyceral dehyde converts into hexose sugar. Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. During this process oxygen gas is released. What do you understand by glycolytic reversal? It is an endothermic chemical process that uses sunlight to turn carbon dioxide into sugars.

In this step of dark reaction, ribulose 1, 5 diphosphate, (also known as ribulose biphosphate), a phosphorylated 5 carbon sugar which acts as carbon dioxide acceptor, combines with carbon dioxide. In C4 leaves the chloroplasts present in bundle sheath cells are of abnormal type. The fall in photo yield beyond red region of spectrum is called “red drop.”, Emerson and his co-worker further extended the previous experiment by supplying additional shorter wavelength of light along with far red light. Answer: The process by which green plants make their own food from carbon-dioxide and water in the presence of sunlight and chlorophyll is called photosynthesis.

Photosynthesis is a physio-chemical process which uses light energy to produce organic compounds. Photorespiration occurs in the chloroplast and may require the help of peroxisomes and mitochondria whereas respiration occurs in cytoplasm and mitochondria. Malic acid is transported to bundle sheath cells, where it is decarboxylated by NADP and specific malic enzyme to produce pyruvic acid and carbon dioxide. Answer: Photorespiration occurs inside photosynthetic cells whereas respiration is found in all living cells. The sunlight controls which reaction of PSII? Photosynthesis also results in the release of oxygen into the atmosphere. Absorption of light by pigment system I (PSI) results in the excitation of its reaction centre P700, which emits electron.

As glucose is a six carbon compound, thus it requires six turns of Calvin cycle to synthesise its one molecule. Thus, we depend upon the process for our existence in more ways than is often considered. c. Name the metabolic processes taking place in the places marked (1) and (2). Pyruvic acid is sent back to mesophyll cells, where it converts to phosphoenolpyruvate by using ATP. The monochromatic far red light which was insufficient, when supplied with shorter wavelength of light enhance the photosynthetic yield and recovered the red drop. What is photosynthesis? Oxaloacetic acid is reduced by NADPH2 to form malic acid in the presence of enzyme, malate dehydrogenase. Photosynthesis occurs in the green tissue of plants. Carbondioxide is again fixed inside the bundle sheath cells through calvin cycle. Levels of carbon dioxide (a reactant) will fall, and levels of oxygen (a product) will rise. Perhaps, the Earth is the only hospitable planet for our lives. Lv 4. With these elements can generate carbohydrates and oxygen.In this sense, carbohydrates provide energy to animals and oxygen is essential for the breathing of living beings. This process is called photosynthesis. The process of making of food by green plants in the presence of sunlight and chlorophyll is known as photosynthesis. This chemical energy is stored in carbohydrate molecules, such as sugars , which are synthesized from carbon dioxide and water – hence the name photosynthesis , from the Greek phōs ( φῶς ), "light", and sunthesis ( σύνθεσις ), "putting … The sugars are used by the cell as energy, and to build other kinds of molecules. Like normal respiration, this process also releases carbon from organic compound in the form of carbon dioxide but does not produce ATP. 2. What is photosynthesis?
