Protista

Classification of protists

Fungus-like, Plant like, Animal Like

Fungus-like protists obtain food how?

Heterotroph decomposers or parasites

Plant-like protist characteristics

Similar to plants Autotrophs Have chlorophyll like pigments Can be unicellular or multicellular

Fungus-like protists

They are protists that absorb their food from dead organic matter. They are grouped into 2 groups, slime molds and water molds. Most fungus-like protists use psuepods, ("false feet") to move around.

Parasite

Type of heterotroph that obtains food from other living organism's bodies

Green Algae

Type of plant like protist Autotroph Multicellular or unicellular Most diverse group of plant like algae

Brown Algae

Type of plant like protist Autotrophs Multicellular Ex: kelp, seaweed Very tall

Red Algae

Type of plant like protist Autotrophs Multicellular Red pigment which allows absorption of light in deep water

Euglenoids

Type of plant like protist Heterotroph or autotrophs Have chloroplasts: like plants Have flagella: like animals Eyespots: like animals Contractile vacuole: like animals.

Dinoflagellates

Type of plant like protist Mostly Autotrophs some decomposers or parasites Mostly unicellular

Diatoms

Type of plant like protist Unicellular Autotrophs Cell walls of cellulose and silica (glass like)

Slime molds

Types of fungus like protists Heterotroph decomposer Unicellular, but may form a community of many nuclei and one large cytoplasm Found in cool, shady, moist areas

Phytoplankton

Unicellular plant-like protist that floats near the surface of the ocean and provides most of the worlds oxygen

Heterotrophs

An organism that obtains its food by feeding on other organisms. Examples include consumers (ex: most animals), decomposers (ex: fungi), and parasites.

Autotrophs

Also called "producers." Produce their own food by using sunlight or heat energy. Plants are a common example of autotrophs.

Pseudopodia

"False feet"- A temporary protrusion of the surface of an amoeboid cell for movement and feeding.

Fungus-like protists are similar to fungi how?

- Reproduction - Obtaining food

Animal like protists

Called Protozoa Unicellular Heterotrophs, many are parasitic Classified by how they move

Plant-like pigment

Chlorophyll

Protozoa classification

Protozoa are animal-like protists of four groups: Amoeba-like Zooflagellates Ciliates Spore-forming

Types of plant-like protists

Red algae, brown algae, green algae, diatoms, dinoflagellates, euglenoids

Spore forming

Type of animal like protist Unicellular All are parasitic Lack cilia and flagella= CANNOT MOVE ON THEIR OWN Love cycle involves tw or more hosts Ex- plasmodium vivax causes maralia and lived in mosquitoes + humans.

Amoeba-like

Type of animal like protists Unicellular Most of these are soft and jelly like Move and eat using pseudopodia

Ciliates

Type of animal-like protist Unicellular They use cilia to move Tiny hair-like projections Have 2 nuclei Micronucleus- controls cell functions Macronucleus- exchange genetic material with other ciliates

Zooflagellates

Type of animal-like protist Unicellular Use flagella to move Some are parasites Ex- gairdia lamblia- lives in the digestive tract of vertebrates Some form beneficial relationships with other organisms

Water molds

Type of fungus-like protist Heterotroph decomposer or parasite Can cause disease Ex: potoato blight and fish ick Unicellular

Decomposer

Type of heterotroph that obtains food from decomposing matter
