Question

The bulk movement of substances through the conducting or vascular tissues of plants is called:

• (A) Translocation
• (B) Transportation
• (C) Cohesion
• (D) None of the above

Answer 1

The Correct Option is A

Explanation:
The bulk movement of substances through the conducting or vascular tissues of plants is called translocation. The higher plants have highly specialised vascular tissues – xylem and phloem. Xylem is associated with translocation of mainly water, mineral salts, some organic nitrogen and hormones, from roots to the aerial parts of the plants. The phloem translocates a variety of organic and inorganic solutes, mainly from the leaves to other parts of the plants.Hence the correct option is (A).
