Question

Name two types of passive absorption in plants.

Answer 1

Answer:

Active absorption uses the symplast pathway, which is the movement of water from cell to cell through the plasmodesmata of the cell. Passive absorption is absorption by the pull from transpiration without the active involvement of the root cells.

Answer 2

Two types of passive absorption in plants:

Passive absorption is type of absorption that occurs along the concentration gradient, either directly through cell membrane, or by means of facilitated diffusion. Examples of passive absorption in plants are:

• Water from the soil is absorbed in plants by means of passive absorption mainly osmosis. Root hair cells absorb the water from soil into them.
• Certain minerals like magnesium etc, which are present in low or trace amounts in the root cells are absorbed passively through root hair cells along with water.
