Question

Angiosperm phloem is characterized by the presence of well-developed sieve tubes and what other specialized cells, which are typically absent in gymnosperm phloem?
Options
A Tracheids
B Vessel elements
C Companion cells
Correct Answer
D Albuminous cells
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 21 mentions 'well-developed sieve tubes and companion cells in phloem' for angiosperms. Page 22 states that gymnosperms 'have no companion cells in their phloem'. Page 16 also contrasts 'Sieve cells, no companion cells' for Gymnosperms with 'Sieve tubes, companion cells' for Angiosperms.

Hint

Consider the cells that functionally assist sieve tubes in angiosperms but are absent in gymnosperms.
