Characteristics |
- Eukaryotic -Unicellular or simple multicellular - Heterotrophic/ Autotrophic - Motile - move through pseudopods (fake feet) e.g. Amoeba, seaweeds |
|
|
Amoeba |
Unicellular, Heterotrophic + lives in fresh water |
|
Structure of Amoeba |
|
|
|
Food Vacuole |
Food ingested by phagocytosis is digested. Ingestible materials are egested in outer membrane. |
|
|
Pseudopods |
Allow amoeba to move and engulf food |
|
|
Cytoplasm |
ECTOplasm: outer layer that slows down osmosis + provides shape ENDOplasm: inner layer flows allow for movement |
|
|
Contractile Vacuole |
- Regulates amount of water in amoeba (osmoregulation: the balance of water + salt levels in an organisms) - If excess water enters the cell by osmosis the contractile vacuole grows, moves towards the surface + releases excess water |
