Question

For optimum photosynthesis crop plants require sufficient
a) Carbon dioxide, plant nutrients and water
b) Radiation, oxygen, plant nutrients and water
c) Oxygen, plant nutrients, water and carbon dioxide
d) Radiation, carbon dioxide, plant nutrients and water
e) All of the above
f) None of the above

Answer 1

For optimum photosynthesis, crop plants primarily require:

d) Radiation, carbon dioxide, plant nutrients and water

Photosynthesis is driven by light (radiation), and plants use carbon dioxide from the atmosphere, along with water, to produce glucose and oxygen. Plant nutrients are also important for overall health and growth but may not be directly involved in the photosynthesis process itself. Therefore, option d is the most accurate choice.
