Question

Secondary tissues of a plant

• A. Add length to roots and shoots
• B. Add diameter to roots and shoots
• C. Both A and B
• D. Help in primary growth of a plant

Answer 1

The correct option is B Add diameter to roots and shoots

Secondary tissues of a plant add diameter to roots and shoots. Secondary growth refers to the growth that results from cell division in the cambium or lateral meristems. It causes the stems and roots to thicken. Primary growth is growth due to cell division at the tips of stems and roots, giving rise to primary tissue. Secondary growth occurs in most seed plants but monocots usually lack secondary growth.

Thus, the correct answer is option B.
