Flashcards
Isogamous Reproduction
Isogamous Reproduction
A form of sexual reproduction in algae where two motile gametes of similar size fuse to form a zygote.
Fragmentation
Fragmentation
A form of asexual reproduction where a parent alga breaks into fragments, each capable of developing into a new individual.

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.
