The presence of mucilaginous coverings helped the first green algae survive in shallow environments.
5
Question
What is the function of rhizoids in primitive green algae?
Answer
Rhizoids serve to anchor the algae to the substrate.
6
Question
Which compound made the spores of the first bryophytes resistant?

12
Question
How do bryophytes reproduce?
Answer
Bryophytes reproduce by spores.
13
Question
What is the dominant phase in the bryophyte life cycle?

What condition is necessary for fertilization in bryophytes?
Answer
Presence of water is necessary for fertilization in bryophytes.
15
Question
What does the antheridium produce in bryophytes?
Answer
The antheridium produces antherozoids (sperm cells).
16
Question
Which structure in bryophytes releases spores?
Answer
The capsule releases spores.

Question
What is the function of rhizoids in bryophytes?
Answer
Rhizoids help in anchorage and absorption.
18
Question
Match bryophyte structures to their functions: Gametophyte, Sporophyte, Capsule, Rhizoid, Antheridium.
