Question

Photochemical reactions of photosynthesis occur in:-

• A. grana lamellae and stroma lamellae of chloroplast
• B. grana lamellae and the fluid stroma of chloroplast
• C. Stroma lamellae and the fluid stroma of chloroplast
• D. the fluid stroma of chloroplast

Answer 1

Answer: (A)

grana lamellae and stroma lamellae of chloroplast

Photochemical reaction is the chemical reaction in plants in which light is absorbed in the form of energy and the electrons generated will be used to produce energy and perform different functions. This photochemical reaction takes place in the granum or stroma lamellae where stacks of thylakoid are present where the photosynthetic pigments are found. When the energy is produced by the light reaction, these energies then go to a stroma region where carbon is present, then it will fix the carbon and it will lead to the formation of glucose.

So, the correct option is 'Grana lamellae and stroma lamellae of chloroplast'.
