Question

Does apoplast provide a barrier to water movement?

Answer 1

Apoplast:

1. Apoplast includes the non-protoplasmic components of the plant body such as cell wall and intercellular spaces.
2. It conducts passive absorption and is a system of adjacent, continuous cell walls.
3. The apoplastic movement of water occurs via the intercellular spaces and cell walls.
4. It does not provide any barrier to the movement of water and it occurs via mass flow.
