Study Notes

Algae Reproduction Types

Isogamy: Involves the fusion of two similar-sized, non-flagellated gametes.
Anisogamy: Involves the fusion of dissimilar gametes, typically one larger and non-motile (egg) and one smaller and motile (sperm).

Vegetative Reproduction

The most common method of vegetative reproduction in algae is fragmentation, where a parent organism breaks into fragments that develop into new individuals.

Form and Size Variability

Algae exhibit a wide range of forms and sizes, from microscopic unicellular organisms to large multicellular macrophytes, such as giant kelp. This diversity allows them to adapt to various environmental conditions.

Asexual Reproduction

The predominant type of spore produced during asexual reproduction in algae is the zoospore, which is motile and capable of swimming due to flagella.
