Question

Study the given figure of the chloroplast and select the correct statement regarding it.

• A. Synthesis of assimilatory power (ATP + NADPH) takes place in the part labelled as Q.
• B. Excess of glucose molecules synthesised during photosynthesis are stored mainly in the form of glycogen represented as R in the given figure.
• C. The photosynthetic reactions that take place in the part labelled as Q are the enzymatic reactions which require the presence of light for their occurence.
• D. The processes involving photolysis of water and evolution of molecular oxygen take place in the part labelled as P.

Answer 1

The correct option is D The processes involving photolysis of water and evolution of molecular oxygen take place in the part labelled as P.

This part of photosynthesis occurs in the granum of a chloroplast where light is absorbed by chlorophyll; a type of photosynthetic pigment that converts the light to chemical energy. This reacts with water and splits the oxygen and hydrogen molecules apart.
