Sexual Reproduction
Most forms of algae reproduce sexually by forming spores. The spores, when cast off the adult organism, develop into male and female gametes which carry only half the genetic information of the parent organism. These gametes are motile, meaning they can move around by themselves, propelled by tiny flagella. When male and female gametes from the same or from different parent organisms combine, the genetic material fuses to create an organism with a full complement of genetic material. This is very similar to the way that ferns reproduce (see the Ferns honor for more details.
Asexual Reproduction
Asexual reproduction is advantageous in that it permits efficient population increases, but less variation is possible. Sexual reproduction allows more variation but is more costly because of the waste of gametes that fail to mate, among other things. Often there is no strict alternation between the sporophyte and gametophyte phases and also because there is often an asexual phase, which could include the fragmentation of the thallus.
