MULTI-CELLULAR ORGANISMS • Are known as Eukaryotic organisms which means they contain a nucleus inside each cell. • Can be heterotrophic- they cannot make their own food. They must consume other plants/animals for energy. • Examples: humans, and animals. • Can also be autotrophic They do not need to feed on other organisms, because they can make their own food through photosynthesis • Examples: Plants or protists
UNICELLULAR ORGANISMS • Can be Eukaryotic or Prokaryotic- Eukaryotic means they contain a nucleus inside the cell and Prokaryotic means they do not contain a nucleus. • Can also be heterotrophic or autotrophic • Examples- Bacteria, Amoeba, Paramecium
PROTISTS • Protists are eukaryotes, with complex cells with nuclear membranes and organelles like mitochondria and chloroplasts. • Includes different types of organisms like algae, protozoans, and slime molds. • Protists are not bacteria or fungi, and they are not plants or animals. • They live in any environment containing water. • Can be heterotrophic or autotrophic as well as multi-cellular or unicellular (most Uni though) • Examples- Amoeba, Paramecium, Volvox
