- Protozoans: they obtain food by phagocytosis
|
|
|
Ciliates protista (example + define)
|
Paramecium (fig 28.11)
- use cilia to move and feed - found in fresh H2O - asexual reproduction - two types of nuclei (one large macronucleus for everyday functions; one to several small micronuclei for the exchange of genetic material between organisms) |
|
|
Pseudopodia protista
|
Rhizopods, incloue amoebas
- move and feed by pseudopodia - asexual reproduction - no flagellated stages in life cycle - inhabit fresh H2O marine and soil habitats |
|
|
Plant-like protista
|
- seaweed
- include green algae (chlorophyta (planktons), charophycaens) - Photosynthetic (chloroplast) - most are freshwater species |
