Solution

The correct option is D
A, B & D

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. But movement through the endodermis layer alone is symplastic.

Q. Explain the symplastic movement and apoplastic movement of water in the cell.

Q. Assertion :During apoplastic movement of water, water travels through the cells and their cytoplasm. Reason: The symplastic movement of water occurs exclusively through the intercellular spaces and the walls of the cells.
