Study Notes
Cyanobacteria
- Characteristics: Oxygenic, photosynthetic, and prokaryotic organisms.
- Gleocapsa: Freshwater cyanobacteria growing in colonial forms of 2, 4, 8, or 16 cells.
- Anabeana: Freshwater cyanobacteria growing filamentously, resembling strings of pearls.
- Oscillatoria: Freshwater cyanobacteria that are unbranched and filamentous, growing like a stack of pennies.
Algae
- Characteristics: Oxygenic, photosynthetic, eukaryotic organisms containing chlorophylls and other pigments.
- Classification Guidelines: Based on types of photosynthetic pigments, cell wall composition, and photosynthetic storage products.
- Chrystophyta: Golden brown algae including diatoms with silica in their cell walls, typically unicellular and found in freshwater and marine environments.
- Euglenophyta: Unicellular, flagellated algae found in freshwater and marine habitats, e.g., Euglena gracilis.
- Chlorophyta: Green algae, can be unicellular, colonial, or multicellular, found in freshwater, soils, and marine locations (e.g., Volvox aureus and Spirogyra).
Protozoa
- Characteristics: Unicellular and heterotrophic organisms lacking a cell wall.
- Classification Guidelines: Determined by their means of locomotion.
- Sarcodina: Protozoa using pseudopods for motility, such as free-living amoebas.
- Ciliophora: Characterized by cilia; notable organisms include Paramecium caudatum and Stentor.
- Mastigophora: Flagellated protozoa, represented by Trypanasoma gambiense, a human parasite causing African sleeping sickness.
- Sporozoa: Non-motile spore-producing protozoa, with Plasmodium as a key organism responsible for malaria.
