Title: How do the bryophytes differ from the seedless vascular plants? Post by: padre on Feb 24, 2011 How do the bryophytes differ from the seedless vascular plants? How are they similar?
Title: Re: How do the bryophytes differ from the seedless vascular plants? Post by: star on Feb 24, 2011 --> the dominant phase of the life cycle.In bryophytes the gametophyte stage is dominant; in seedless vascular plants the sporophyte is dominant.
--> the absence/presence of vascular tissue. Bryophytes contain no vascular tissue. As a result, they do not have true stems, roots, or leaves. --> the absence of guard cells in bryophytes. Both bryophytes and seedless vascular plants have air spaces in their structure for gas exchange. However, the bryophytes do not have guard cells associated with their air spaces. Guard cells allow plants to control the size of the stomata. In most other major features (listed in the table), these two groups are similar. |
