|
B mesophyll

|
|
C root hair

D root hair

Explanation:
Detailed explanation-1: -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-2: -Epidermis, Cortex, Root Hair, Xylem, Endodermis.
Detailed explanation-3: -Soil→Root hair→Cortex→Endodermis→Pericycle→Protoxylem→Metaxylem.
Detailed explanation-4: -Water absorbed by the roots from the soils (Endomosis), passes up the trunk (Ascent of Sap) through the xylem, reaches the tissues of the leaves through veins and then evaporate from the surface. (Transpiration)
