Study Notes
Photosynthesis Organisms
- Photosynthesis occurs in plants, algae, certain protists, and some prokaryotes.
Protists
- Protists are eukaryotes.
- Protists have various organizational forms: unicellular, colonial, filamentous, or parenchymatous.
- Protists lack vegetative tissue differentiation (except for reproduction).
- Examples of protists include paramecium, euglena, and amoebas.
Prokaryotes
- Prokaryotes are single-celled organisms.
- Prokaryotic cells lack a nucleus and other membrane-bound organelles.
- Examples of prokaryotes include blue-green algae, bacteria, and mycoplasma.
Food Source
- These photosynthetic organisms are a crucial food source for most living things.
