Place in order the correct sequence by which water flows through plants
kotykmax [81]

Answer:

The correct sequence is - 2, 3, 4, 1.

Explanation:

The movement of the water takes place in the plant from the soil and moves up to leaves and from there to the atmosphere. Root hairs help in the absorption of the water from the soil with help of the epidermis of root hairs. Water then takes the path from the root to the stem with help of cortical cells.

Once the water reaches the endodermis or endodermal cell the water freely flow in the xylem cell upwards the stem moves to leaves by the transpiration stream. In the process of transpiration, an excess amount of water evaporates into the atmosphere.
