Transcript of Kingdom Protista

Kingdom Protista
Anaerobis vs. Aerobic
Aerobic is when the organism uses oxygen
Anaerobic is where the organism doesn't use oxygen
Some Protists are Aerobic and Anarobic
Physiological Features
Gas exchange: occurs through diffusion
Nutrition: Protozoans are catagorized as heterotoph therefore they do not make their own food
Digestion: Protozoans have an intracellular digestion
Respiration: Is primiarly an aerobaic process but also accomplished by diffusion
Cell Wall Present
Sometimes present but first...
Different types of Protist
Fungi-like and plant like protist have a cell wall made of cellulose
Animal-like protest do not have cell wall
Asexual vs. Sexual Reproduction
Sexual Reproduction-
2 parents needed (male and female)
Genetically different
1 parent needed (male or female)
Genetically identical
Protists can reproduce sexually or asexually (may alternate)
Diagram of Amoeba
Autotroph vs. Heterotroph
Autotrophs producde their own food using photosynthesis and other processes.
Heterotrophs get food from others.
Protists are either autotrophs or heterotroph dependent on the type.
Unicellular vs. Multicellular
Some Unicellular, Some Multicellular.
Depends on what type of protists it is.
Euglenozoa, Alveolates, Diatoms, Chrysophyta, Choanoflagellates, etc.
Red Algae, Brown Algae, Omycetes, Mycetotes, etc.
Majority of protists are motile
Using Cilia-little hair like structures on the cell membrane
Using flagella- A tail extending outside the cell.
Anatomical Features
protists are only seen with microscopes
protists have characteristics of both plants and animals
some are unicellular and some others are multicellular.
protists are propelled by tiny hair called cilia
They are encased with glassy silica based shells or wound pellicles of protein strips.
