General characters of Algae (Reproduction and Life cycle)
Algae reproduce by vegetative, sexual and asexual methods.
Sexual reproduction may be isogamous, physiologically anisogamous or oogamous type.
Asexual reproduction takes place by zoospores, aplanospores, hypnospores, autospores, endospores etc.
Algae show progressive evolution in sexuality.
The motile vegetative cells, zoospores and gametes of algae (except the class Rhodophyceae and Cyanophyacae) show a pair of flagella. Each flagellum shows 9+2 arrangement of fibrils.
Algae exhibit haplontic life cycle or diplontic life cycle, haplodiplontic life cycle, haplobiontic life cycle and diplobiontic life cycle.
