G11 Pre-AP Biology Characteristics:
- Mainly unicellular
- Under Eukarya domain.
- Eukaryotic cells.
- Reproduces sexually and/or asexually.
- Diverse, not closely related.
Classification:
- Animal-like (protozoans):
- Heterotrophs.
- Can move.
- Plant-like:
- Autotrophs, can photosynthesize.
- Photoautotrophs.
- Some are capable of consuming other organisms when light is unavailable.
- Can be unicellular or multicellular.
- Fungus-like:
- Absorbs nutrients from other organisms.
- Heterotroph/decomposers, outer digestion.
- Cell wall is not chitin.
- Examples are slime moulds and water moulds.
| Phylum | Characteristics | Example |
|---|---|---|
| Cercozoan | Pseudopods, temporary cytoplasmic extension for movement/feeding. | Amoeba proteus |
| Cilliophora | Cilia, short hair like extensions for sweeping food or movement. | Paramecium caudatum |
| Zoomastigma | Flagella, long tail like whip. | Trichonympha |
| Sporozoa | Vector, uses living organism to transmit infection from one organism to another. Parasitic to animals. | Plasmodium vivax (causes malaria) |
| Myxomycpta | Many nuculei, engulfs like amoeba. | Plasmodia |
| Acrasiomycota | Individual amoeboid cells, one nuculeus. | Cellular slime mold |
| Oomycota | Filamentous, resemble fungi, release enzymes to absorb nutrients. | Water mold |
| Paramecium: |
- Cilia.
- Asexual (binary fission/sexual.
- Gullet.
- Outer protein covering.
- Lives in water. !Pasted image 20260924105000.png Amoeba:
