(ii) Gymnosperms lack tracheids and vessels.

Anatomy of Flowering Plants

Solution:

Phloem parenchyma is absent in most of the monocots and some herbaceous dicots. Gymnosperms lack companion cells, instead they possess albuminous cells. Gynmosperms lack vessels (except Gnetum etc.) but possess tracheids. Infact, tracheids constitute $90-95\%$ of wood in gymnosperms.
