Read the following statements and choose the following option: 1. Water is is not a reactant in light reaction 2. Water stress causes the stomata to open 3. Cornelius van Niel demonstrated that photosynthesis is essentially a light-dependent reaction in which hydrogen from a suitable oxidisable compound reduces carbon dioxide to carbohydrates. 4. CH2O represents a carbohydate

Options

  1. AOnly 2 is correct
  2. BOnly 4 is correct
  3. CBoth 2 and 3 are correct
  4. DBoth 1 and 2 is incorrect

Correct answer

D. Both 1 and 2 is incorrect

Step-by-step solution

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. Water stress causes the stomata to close hence reducing the CO2 availability.
