Rightwards Arrow the dominant phase of the life cycle.In bryophytes the gametophyte stage is dominant; in seedless vascular plants the sporophyte is dominant.

Rightwards Arrow the absence/presence of vascular tissue. Bryophytes contain no vascular tissue. As a result, they do not have true stems, roots, or leaves.

Rightwards Arrow 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.
