Read the following statements and choose the following option: 1. There are three photosystem 2. Water stress decreases the surface area of leaves 3. Photosynthesis is the secondary source of all food on earth 4. Jan ingenhousz discovered oxygen in 1774. 5. The O2 released is from water; this was proved using radio isobar techniques

Options

  1. AOnly 1 is correct
  2. BOnly 2 is correct
  3. CBoth 4 and 5 is correct
  4. DBoth 1 and 2 is incorrect

Correct answer

B. Only 2 is correct

Step-by-step solution

Water stress makes leaves wilt, thus, reducing the surface area of the leaves and their metabolic activity as well.
