participates directly in the light reactions of photosynthesis and is the most essential type of chlorophyll; chlorophyll b, which is similar to chlorophyll a although it participates in photosynthesis indirectly and absorbs blue and orange light; and carotenoids, which is the...
Photosynthesis occurs in chloroplasts, the green-colored organelles found in plant cells. It can be divided into two main stages: Light-dependent reactions: This stage takes place in the thylakoid membranes of chloroplasts. Light energy, usually from the sun, is absorbed by pigments like chlorophyl...
What is the first step in photosynthesis?? Formation of ATPIonization of waterAttachment of carbon dioxide to five carbon sugarExcitement of an electron of chlorophyll a by a photon of light 相关知识点: 试题来源: 解析 Excitement of an electron of chlorophyll a by a photon of light ...
Honestly the situation has a potentially deadly consequence and we should invest money now into photosynthesis research as to avoid major issues in the near and far future. Byronburg44— On Oct 06, 2010 @thumbtack, while your statement seems very altruistic the unfortunate part is the logical fa...
Green seed photosynthesis is characterized with a large antenna size of Photosystem II (PSII), which enables the seeds to deal with low light saturation point and operate under a lower level of plastoquinone pool than in the leaves. In addition to the above features, the low chlorophyll (Chl...
阅读理解(1).What does O2 mean in Chinese? A. 二氧化碳 B. 钾 C.氧气 D.氮气(2).What is in leaves? A. Energy B. O2 C. Chlorophyll D. CO2 (3).What can photosynthesis(光合作用) produce for living things? A. Sugar B.O2 C. CO2 D. A and B(4).How can we get more O2 acco...
What are the steps in photosynthesis? What is the function of the photosynthetic pigments in the overall process of photosynthesis? What is the role the stoma play in photosynthesis? Why does O2 come from H2O in photosynthesis? What are the roles of chloroplasts and chlorophyll in photosynthesis?
Chlorophyll is the green photosynthetic pigment present in chloroplasts which provides the energy necessary for photosynthesis. The intense green color of chlorophyll is due to its strong absorbencies in the red and blue regions of the electromagnetic spectrum, and because of these absorbencies the ...
