You are given an unknown plant to study in the laboratory. You find that it has chlorophyll, no xylem. Its multicellullar sex organs are enclosed in a layer of jacket cells. Its gametophyte stage is free living. The plant probably belongs to
1 Chlorophyceae
2 bryophyte
3 pteridophyte
4 gymnosperm
Explanation:
(b)According to the features described; the unknown plant belongs to bryophytes. Bryophytes refer to a group of plants comprising the mosses, liverworts, and hornworts. They do not have a true vascular system and are unable to pull water and nutrients up from the ground at any significant distance. This distinguishes bryophytes from ferns and flowering plants.
