Question

Which of the following statements is incorrect?

• A. Less than 1 per cent of the water reaching the leaves is used in photosynthesis
• B. Most of the water flow in the roots occurs via the apoplast pathway
• C. Suction through a straw is an example of positive hydrostatic pressure.
• D. Turgor Pressure is responsible for enlargement and extension growth of cells.

Answer 1

Answer: (C)

Most of the water flow in the roots occurs via the apoplast since the cortical cells are loosely packed, and hence offer no resistance to water movement. Less than 1 per cent of the water reaching the leaves is used in photosynthesis and plant growth.
