Question

When the rate of respiration is more than the rate of photosynthesis.
1. Plant will die.
2. Storage food comes to end.
3. The quantity of $O_2$ decreases in the atmosphere.

• A. 1 true
• B. 2 true
• C. 1 and 2 true
• D. 2 and 3 true

Answer 1

The correct option is A 1 true

When the process of respiration is taking place at a faster rate as compared to photosynthesis, there is more breakdown of the food than the process of production. This will result in less production of food and eventually, the process will be shut off. All the reserves of the plant will be used as respiratory substrates. This will cause starvation of the plant and the plant will die.

Thus, the correct answer is option A.
