Question

Which of the following statement are false?
(a) Most cells are tiny with volume range of $1-100$ $n{m}^3$
(b) Some cells have microvelli to increase the absorptive surface area.
(c) All cells arise from pre-existing cells.
(d) In plants, translocation of solutes is performed by xylem vessels and tracheids.
(e) According to cell theory, all cells arise from abiotic material.

• A. a), c) and e) are false.
• B. a), d) and e) are false.
• C. b), c) and d) are false.
• D. c), d) and e) are false.

Answer 1

Answer: (B)

a), d) and e) are false.

Tracheids (top) and vessel elements (bottom) are the water-conducting cells of xylem tissue. Phloem tissue is responsible for translocation, which is the transport of soluble organic substances, for example, sugar.

All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.

Hence the correct answer is (B)
