Study Notes
Protozoa Overview
- Protozoa are unicellular eukaryotic organisms.
- They possess a true nucleus and membrane-bound organelles.
Classification
- Protozoa are classified as diverse groups of unicellular organisms.
- Historically viewed as single-celled animals due to animal-like behaviors.
Locomotion Types
- Phylum Sarcodina: Utilize pseudopodia for amoeboid movement.
- Phylum Ciliophora: Characterized by cilia, similar to but shorter than flagella, aiding in movement.
- Phylum Zoomastigina: Move via whip-like flagella.
- Phylum Sporozoa: Have an apical complex structure, facilitating their unique type of movement.
Nutritional Modes
- Protozoa are heterotrophic, meaning they ingest or absorb organic material for nourishment.
- In contrast, algae (plant-like protists) are autotrophic and use photosynthesis.
Reproduction
- Common asexual reproduction method is binary fission, where the organism divides into two.
- Other asexual reproduction methods include budding and schizogony.
- Some protozoa can also reproduce sexually.
Tissue Differentiation
- Protozoa lack tissue differentiation and exist as single-celled organisms.
- They inhabit diverse environments and can be free-living or parasitic.
- Infections caused by protozoa can vary from asymptomatic to severe, depending on the species and host.
