Assertion. Active transport does not occur through a non-living semi-permeable membrane.

Reason. Active transport is in a direction opposite to that of diffusion, i.e., from a region of lower concentration to higher concentration.

1. Both A and R are True
2. Both A and R are False
3. A is True and R is False.
4. A is False and R is True.

Assertion. Lenticels allow diffusion of gases for respiration.

Reason. Lenticels are located on the surface of older woody stems. They close during night time and open during the day for the process of transpiration.

1. Both A and R are True
2. Both A and R are False
3. A is True and R is False.
4. A is False and R is True.

Assertion. Nerium leaves have sunken stomata covered by trichomes.

Reason. Nerium is a hydrophytic plant which gets rid of excessive water through the process of transpiration.

1. Both A and R are True
2. Both A and R are False
3. A is True and R is False.
4. A is False and R is True.

Assertion. Transpiration helps in the descent of sap by producing a suction force acting from the top of a plant.

Reason. Transpiration is the evaporative loss of water through the aerial parts (leaves, stems) of a plant. However, this loss holds much significance for the plant.

1. Both A and R are True
2. Both A and R are False
3. A is True and R is False.
4. A is False and R is True.
