What are the distinguishing features of club mosses, whisk ferns, and horsetails? How they differ from ferns?
These are types of bryophytes, the only group of plants that do not have vascular tissue. Because they don’t have vascular tissue, they are fairly small so all their cells can be near water. Also, in bryophytes, the gametophyte is the dominant generation, rather than the sporophyte (which is the dominant generation in ferns).
