Question

What is apoplast movement in plants?

Answer 1

Apoplast:

1. Except for the Casparian strips of the endodermis in the roots, the apoplast is a system of contiguous cell walls that runs throughout the plant.
2. It is one of the paths through which water, along with ions, moves into xylem cells of roots.

Apoplast movement in plants:

1. The intercellular spaces and cell walls are the only places where movement occurs.
2. The gradient determines the movement.
3. The movement of water is through mass flow.
4. The cohesive and adhesive characteristics of water cause mass flow.
