Chapter 29 - 29.2 - Concept Check: 2

Answer

One example is swimming sperm, which can reach female structures since bryophytes live in moist habitats where films of water, through which the sperm can swim, often occur. A second example is the small, tough, drought-resistant spores of bryophytes which can successfully disperse on the wind. A third example is the capsule, in which spores are made and from which they disperse. It is held well above the rest of the bryophyte so that the wind can have free and easy access to it and the spores.
