Current Question (ID: 12452)

Question:

Phloem of gymnosperm consist of

Options:

1. Albuminous cells and Sieve cells
2. Sieve tubes and companion cells
3. Phloem parenchyma and phloem fibres
4. None of the above

Solution:

The phloem of gymnosperms is composed of sieve cells and albuminous cells. Unlike angiosperms, gymnosperms lack companion cells, which are specialized cells that support sieve tubes and aid in phloem transport. Instead, gymnosperms have albuminous cells that are associated with sieve cells and play a similar role in maintaining phloem function. Phloem parenchyma and phloem fibers may also be present in gymnosperms, but they are not the primary cell types of the phloem tissue.
