The factors that can be limiting for the light independent reactions of photosynthesis are:
1. , temperature, and light
2. , light, and water
3. water, temperature, and
4. oxygen, water, and temperature
Except for plants in shade or in dense forests, light is rarely a limiting factor in nature. This is because:
1. Dark reactions do not depend on light
2. The rate of photosynthesis can be increased by higher carbon dioxide and lower temperatures even in low light conditions
3. Light saturation occurs at 10 % of full sunlight
4. Carbon fixation is independent of enzymes

I: | Water stress can cause the stomata to close, hence, reducing the carbon dioxide availability. |
II: | Water stress also makes leaves wilt, thus, reducing the surface area of the leaves and their metabolic activity as well. |
1. | Only I | 2. | Only II |
3. | Both I and II | 4. | Neither I nor II |
