Reproduction in algae takes place either Asexually or Sexually.
-
Asexual Reproduction: They are of three types.
-
Fragmentation: The thallus breaks into smaller fragments each of which gives rise to another thallus.
-
Spores: They are produced in vegetative cells or in specialized structures called sporangia. They non motile spores are called aplanospores and the flagellated motile spores are called zoospores.
-
Binary fission: Nuclear division followed by cytoplasmic division.
-
Sexual Reproduction: In sexual reproduction, male and female gametes unite to form a diploid zygote. The eggs are formed within the oogonia and sperms are produced in male reproductive structures called antheridia.
