Question

Identify the true statements given below
I. Gymnosperms have albuminous cells and sieve cells
II. Phloem fibres are made up of collenchyma cells
III. Phloem parenchyma is absent in most of the dicots
IV. Most of the Gymnosperms lack vessels in their xylem

• A. I & II
• B. II & III
• C. I & IV
• D. III & IV

Hint:

Gymnosperm xylem = tracheids (no vessels), phloem = sieve cells + albuminous cells.
Phloem fibres = sclerenchyma.
Recall structural differences between gymnosperms and angiosperms for quick answers.

Answer 1

The Correct Option is C

1. Gymnosperms characteristically have sieve cells (rather than sieve tube elements) and associated specialized albuminous cells (analogous to companion cells in angiosperms) — statement I is true.
2. Phloem fibres are sclerenchymatous (sclerenchyma), not collenchyma — statement II is false.
3. Phloem parenchyma is generally present in many dicots — statement III is not a correct generalisation.
4. Most gymnosperms lack true vessels in xylem and instead have tracheids — statement IV is true.
5. Therefore the true statements are I and IV. Hence the correct answer is (3) I & IV.
