|
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.
