Study Notes
- Algae are photosynthetic aquatic organisms.
- Algae reproduce both asexually and sexually.
Classification of Algae
- Chlorophyta: green algae
- Rhodophyta: red algae (cell walls contain agar)
- Phaeophyta: brown algae
- Chrysophyta: golden and yellow-green algae and diatoms, cell walls contain silica
- Diatoms are a significant source of the earth's oxygen.
Protozoans
- Protozoans: eukaryotes, unicellular organisms lacking a cell wall.
- Most protozoans are motile and need a moist environment to live.
- Trophozoite: the motile, active, feeding stage of a protozoan.
- Cyst: the dormant form of a protozoan that is present in unfavorable conditions.
Life Cycle of Protozoans
- Protozoans reproduce asexually through schizogony.
- Schizogony: the nucleus divides multiple times before the cell divides.
