Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
here is the correct order of root parts from the highest to the lowest water potential ____
A
epidermis-cortex-endodermis-xylem
B
epidermis-endodermis-cortex-xylem
C
xylem-endodermis-cortex-epidermis
D
xylem-cortex-endodermis-epidermis
Explanation: 

Detailed explanation-1: -Epidermis, Cortex, Root Hair, Xylem, Endodermis.

Detailed explanation-2: -The sequence in order from outer to the inner side in the transverse section of a plant root will be root hair, epidermis, cortex, endodermis, xylem.

Detailed explanation-3: -Hence, the correct sequence from outer to inner layers is soil water, root hair, cortical cells, endodermis, and xylem. Was this answer helpful?

Detailed explanation-4: -1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3-Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

Detailed explanation-5: -The water first enters the protoxylem and then into the metaxylem. From xylem, the water moves up and reaches the other plant parts.
