At 2 – It is the structure of extracellular DNA that is responsible for replication of chloroplasts when necessary in the photosynthesizing cells. b) It involves the breakdown of glucose and is a catabolic process. Flowers serve a reproductive purpose, so again, there's no reason for plants to use them for photosynthesis. It's an entry to the mid-level quiz, so, try to answer all the ten questions you face. c.

The process of photosynthesis primarily occurs in leaves of all green plants. During this process ATP, CO. b. Illustrate the relationship between light and photosynthesis (i.e., you need light source for plants to grow; more light more photosynthesis) 3. Go Back to Biology Home Page Physics Chemistry Maths. Here electrons are extracted from water and are known as water splitting centre, and is catalyzed by the Mn+ and Cl– ions. Only one type of chloroplasts is present. It breaks down the proton gradient to release energy i.e. Find out how Melvin Calvin worked out the complete biosynthetic pathway for synthesis of sugar. a) In the reaction centre, PS II, situated in the inner surface of the thylakoid membrane. If yes, How? The colour of leaf stored in dark changes from green to pale green or yellow in colour. During light reaction in photosynthesis the following are formed: Dark reaction in photosynthesis is called so because, The correct sequence of flow of electrons in the light reaction is, a. PSII, plastoquinone, cytochromes, PSI, ferredoxin, b. PSI, plastoquinone, cytochromes, PSII, ferredoxin, d.
