During monsoon, the rice crop of eastern states of India shows lesser yield due to limiting factor of
1 \(\mathrm{CO}_{2}\)
2 Light
3 Temperature
4 Water
Explanation:
According to law of limiting factors given by Blackman, when a process depends upon a number of factors which are separate, the rate of the process is limited by the pace of the slowest factor. Rate of yield is dependent on light as photosynthesis is dependent on light. During monsoon, the light is dim and so this reduces rate of photosynthesis and hence yield.

In which of the following climate plants usually show higher temperature optimum w.r.t. each other?
1 Tropical
2 Temperate
3 Tundra
4 None of the above
Explanation:
The temperature optimum for photosynthesis of different plants also depends on the habitat that they are adapted to. Tropical plants have a higher temperature optimum than the plants adapted to temperate climates.

i. Water ii. Leaf orientation iii. Temperature iv. Genetic predisposition v. Age of leaves Among the given factors, which factors affect photosynthesis?
1 i, ii, iii
2 ii, iv, v
3 ii, iii, iv
4 All of the above
Explanation:
Photosynthesis is under the influence of several factors, both internal (plant) and external. The plant factors include the number, size, age and orientation of leaves, mesophyll cells and chloroplasts, internal \(C{O_2}\) concentration and the amount of chlorophyll. The plant or internal factors are dependent on the genetic predisposition and the growth of the plant.The external factors would include the availability of sunlight, temperature,\(C{O_2}\) concentration and water. As a plant photosynthesises, all these factors will simultaneously affect its rate.

Rather than directly on photosynthesis, where is the effect of water as a factor?
1 Through effect on the photorespiration
2 Through effect on the plant indirectly
3 Through effect on the photorespiration indirectly
4 Through its effect on the plant directly
Explanation:
Even though water is one of the reactants in the light reaction, the effect of water as a factor is more through its effect on the plant, rather than directly on photosynthesis.
