Question

The movement of water through root layers is ultimately symplastic in the endodermis. Give a reason?​

Answer 1

May be due to xylem tissues

Answer 2

Answer:

The water movement through root is symplastic in the endodermis due to the presence of Casparian Strips.

Explanation:

Symplast is present on the inner side of the plant’s plasma membrane, and is usually a network of connected protoplasts for simple solutes to diffuse quickly.

Like we already know, the water movement through the root layers is basically symplastic within the endodermis. This is due to the presence of Casparian strips.

Water is first absorbed by the root hairs through simple diffusion, which then travels through the xylem. Here, the endodermis has hydrophobic Casparian strips in the cell walls. Here, water is pushed into the symplasts, because of the evident hydrophobicity.
