The protists form a group of organisms that really do not fit into any other kingdom.
Although there is a lot of variety within the protists, they do share some common
characteristics.

65,000 species half are extinct
1) Energy: Can be either heterotroph or autotroph depends on their classification
2) Reproduction: Asexual most of the time..some can sexually
3) Made of Cells: singlecelled or multicelled
4) Respond to Stimuli:
some move to the bottom in response to light
some have trichocysts shoot out for protection
some have eyespots that detect light and move towards it5) Grow and Develop: very simple, but still get larger and mature
Habitat = Moist environments

PlantLike Protists Known as algae
Unicellular, multicelled, or live in colonies
Have chloroplast = photosynthesis = autotrophs
Can live in soil, bark of trees, fresh water, and salt water
Important because they produce a lot of oxygen for other living things
Unlike plants, however, plantlike protists do not have true stems, roots, or leaves
examples: kelp, sea weed, phytoplankton

AnimalLike Protist known as protozoa
heterotrophs eat food
single celled = microscopic
can move
some cause diseases
examples: paramecium, amoebas, euglena

FungusLike Protist heterotrophs feed on decaying materials
reproduce by spores
usually do not move
examples: slime molds and water molds
1) Slime molds = saprophytic
2) Water molds = parasitic
lives in cool, dark places

MovementProtists move in 3 different ways:
1) Flagellum
2) Cilia
3) Pseudopod

Flagellum
long whip like tail use to move or catch food.
Example Euglena

Cilia small, hair like structures around the surface of protist.
sweeps food into mouthlike structure
cilia beat/sway to a rhythm to move
Example: paramecium

Pseudopod means false foot
a finger/foot like projection of the cell membrane
used to catch food and move
Example: Amoeba
