Question

Photosynthetic pathway which occurs in tropical grass plants is

• A. Hill Reaction.
• B. Calvin Cycle.
• C. Blackman reaction.
• D. Hatch and Slack cycle.

Answer 1

The correct option is D Hatch and Slack cycle.

Hatch and slack cycle takes place in C4 plants. In these plants, there are two types of cells namely mesophyll cells and bundle sheath cells. Carbohydrate, the end product is synthesised in bundle sheath cells. C4 plants have high photosynthetic efficiency due to their ability to fix carbon dioxide in environmental conditions where its concentration is less hence seen in tropical grass plants. Thus the correct answer is option D.
