Question

Translocation of solutes primarily takes place through______________.
A. Phloem
B. Xylem
C. Cortex
D. Pith

Answer 1

Hint: In translocation of solutes, food produced by the leaves is transferred from the leaves to other parts of the body. Vascular tissue is a complex conducting tissue found in vascular plants, composed of more than one cell type.

Complete answer:
-Translocation can be done through the phloem. Translocation can be defined as the process of the movement of the food material from the leaves to roots, stem, and flower. Phloem allows the upward and downward movement of the solute. Phloem is a vascular tissue which involves in the conduction of the food material from leaves to other parts of the plant. It is of four types, and these are sieve tube, cambium cell, phloem parenchyma and phloem fibre.
-Xylem is the vascular tissue which conducts the movement of the water and minerals from the root to other parts of the plant. Xylem is involved in the upward movement only. Xylem is of four types, and these are tracheid, vessels, xylem parenchyma, and xylem fibres.
-Pith are the soft and spongy parenchymatous cells which are present in the stem. They store the nutrients for the plant and transport it throughout the body. The ring of the xylem surrounds pith.
-Cortex is the region present between the epidermis and vascular bundle of the stem and root of the plant. The cells of the cortex stored material such as carbohydrates, resin, latex, and other essential oil.

Hence, the correct answer is option (A).

Note: Both xylem and phloem are the vascular tissue which is involved in the conduction of the material, but phloem is involved in the translocation of solute. The xylem and phloem are the principal components of vascular tissue. These two tissues internally transport fluid and nutrients.
