Protists!!!
Protists
Protists can be defined as single-celled organisms that contain a nucleus
Protists
Protists live in: Watery environments Moist soil Live inside larger organisms
Protists
Characteristics Can be autotrophic or heterotrophic Most live as individual cells Some live in large colonies
Protists
3 Major kinds of Protists Animallike Plantlike Funguslike
Protists
The animallike protists are broken down into 4 major groups Sarcodines Ciliates Zooflagellates Sporozoans
Sarcodines
Sarcodines can be identified by their pseudopods or “false-foot” Pseudopod is a footlike extension that an
amoeba uses to move and capture food Ex. Amoeba (NNN) VIDEO!!!
Ciliates
Ciliates have small hairlike projections on the outside of their cells Cilia act like tiny oars to move the
organism Ex. Paramecium Stentor, Spirostomum
Zooflagellates
Zooflagellates are animallike protists that move using a flagella (usually 1-8 flagella)! Many kinds live inside other organisms
as symbionts a few are parasites Ex. Giardia
Sporozoans
All sporozoans are parasites that feed on the cells and body fluids of their host animals
Ex. Plasmodium malaria
Plantlike Protists
Plantlike protists capture energy from the sun using chloroplasts
Plantlike Protists
Three major groups of plantlike protists Euglenas Diatoms Dinoflagellates (WHICH IS WHICH????)
Euglena
All possess two flagella, eyespots (why?!), and green structures used in photosynthesis
Diatoms
Diatoms are plantlike protists made of a tough glasslike, silicon material
Dinoflagellates
Dinoflagellates are plantlike protists that have two flagella and armor like cell walls
Fungus-like Protists
Fungus-like protists are heterotrophic, have cell walls, and use spores to reproduce. An example are slime molds.
Adios, ameobas…
