Protists (74-83)
What is a Protist
Animal-Like Protists
Plantlike Protists
Funguslike Protists
Eukaryotes that cant be classified as animals, plants or fungi
all live in moist surrounding
Protists very in many different ways such as: speed, cells, and ways of getting energy
Protozoans With Cilia
Protozoans with Flagella
Protozoens with Pseudopods
Protozoans that are parasites
Protozoens who live in frash water have a contractile vacuole that realeses exes water from the cell
Pseudopods are temeorary bulges of the cell, they are formed when the cytoplasm flows toward one place and the rest of the organism follows
group called the ciliates
Thease are called the sarcodines
Ciliates are hairlike things sticking out of the cell
Ciliates use cilia to get food and move
This group is called the flagellates
Flagella are long whip like, tentical like things that the cell use to move
Some of these live in other organisms and can hurt or help there hosts bodys, when at least one organisms benifits this relatiponship is called symbiosis, when both benifit it is called mutualism
Some can have multiple hosts in their life, some move by flagella some move with the host
Feed on the cells and the body fluids of their hosts
can cause many bad diesieses within the host
Commonly called algea, all are autotrophs
Diatoms
Red algea
Dinoflagellates
Green algae
Euglenoids
Brown algae
butiful glass like cell walls, unicellular
Some float on top of the water, some attach to objects near the surface of the water
Dead cells of the diatoms gather at the bottom of the ocean, this stuff is used for poloshing and insect repelant
Unicellular, surrounded by stiff plates that look like armor
Use two flagella to twirle through the water
Can glow in the dark, and often light up the surface of the water
Some can be heterotrophs when light is not available, but when light is they are autotrophs
Green and unicellular
Use red pigments to absorb small ampounts of light from the surface
Some can grow to as much as 250 meters long
most are multicellular seaweeds
Similar to the plants that live on land, but most live in the water
most are unicellular, contain green pigments
most things that people call seaweed are brown algae
Most are pretty big and, have gas filled sacs which allow them to flooat upright in the water
Slime molds
Water molds and downy mildews
live in dark moist places
Start as small ameba and then grow into masses that can get big or small, then when there envirnment gets rough they realese pores and the process starts over
Found in moist places, often grow in tiny fuzz like threads
can attack crops and cause famine
