Q:

What phase of the bryophyte life cycle is dominant?

A:

Quick Answer

The phase of the bryophyte life cycle that is dominant is the haploid gametophyte. Bryophytes reproduce through spores and they do not produce flowers or seeds. Gametophytes produce sperm and eggs or gametes in a special cell called a gametangium.

Bryophytes do not have true roots; instead, they have root-like protuberances called rhizoids that do not take out water and minerals from the substrate. To reproduce, bryphotes require a damp environment.
