Protists |
Most diverse kingdoms , More than 200,000 species , Three Different Phyla: animal like(protozoans), plant like(algae), fungus like(slime and water molds)general |
|
General Characteristics |
Autotrophs and heterotrophs Eukaryotic cells that are capable of movement Mostly unicellular but could be millions of cells Live in many different environments |
|
Animal like protists(Protozoans) |
Some free living; some parsites Free living live in any habitat at some time during the year Many species make up zooplankton, primary source of energy in aquatic ecosystems (base of food chain) Some love in the soil Parasitic protozoan usually have complex life cycles that take place in cells, tissues, and bloodstream of their host. |
|
Reproduction |
Asexually usually by binary fission Multiple fission, a form of cell division that results in a number of identical individuals |
|
Sarcodines |
•include hundreds of amoebas inhabitat freshwater, saltwater, and soil •live on other protists which they engulf by phaycocytosis(surrounds the food with its pseudopodia) •contractile vacuoles organelles move excess water • foraminiferans and radiolarians have a hard outer layer covering •when these die, the shells make huge deposits of limestone called chalk |
|
Pseudopodia |
Move by extending lobes of cytoplasm |
|
Slme Molds |
Spend half their life in a mobile, amoeba like feeding form, engulfing organic matter and bacteria like Protozoa Produce fungus like reproductive structures which is why they were once classified as fungi Typically found growing on damp soil, rotting logs , decaying leaves, or other decomposing organic matter in most areas During reproduction, slime molds produce a spore bearing structure called a fruiting body |
|
Multiple fission |
Form of cell division that results in a number of identical individuals |
|
Contractile vacuoles |
Removes excess water |
|
Macronulcleus |
Large nucleus in ciliates |
|
Micronucleus |
Small nucleus |
|
Paramecium Eats |
When eating, the cilia sweeps food particle such as microscopic algae and bacteria into the oral groove, in the oral groove, the mouth pinches off around them to form food vacuoles |
|
Plasmodium's Life Cycle |
A malaria infected female mosquito human host. Sporozoites infect liver cells and mature into schizonts, which rupture and release merozoites. |
|
Algae |
Algae are not plants because it has chlorophyll and can manufacture their own food through the process of photosynthesis |
|
Amoebas |
As cysts can spread by water, in food, or on dishes causing ameboid dysentery which can be fatal |
