Protista and Fungi

Kingdom Protista

To be a protista you must: Be a eukaryotic organisms Most are unicellular but a few are

multicellular If’s it’s NOT archaebacteria, eubacteria,

fungi, plant or animal

Kingdom Protista

Three Classifications (eating habits) 1. Plant-like Protista

Produce their own food by photosynthesis.

2. Animal-like Protista Heterotrophs

3. Fungi-like Protista Decomposers

Plant-Like

Plant-like protista are one celled organisms that have the ability to photosynthesize.

make up the base of aquatic food chains phytoplankton makes up half of the

photosynthesis that occurs on earth (oxygen) can cause Red Tides - algal blooms - which

are toxic Brown, Green, and Red algae

Phytoplankton is considered the base of the aquatic food chain. Why? And what would be the equivalent of phytoplankton on terrestrial surfaces?

Examples

Kelp Forest

A unicellular, eukaryotic organism that has a flagellum and is photosynthetic should be classified in Kingdom Protista.Why would this be within the kingdom Protista and not within the plant kingdom?

Animal- Like

Animal-like protista are unicellular and are heterotrophic.

All animal-like protista can move and are called PROTOZOAN

There are 4 types: 1. Pseudopods, 2. Ciliates, 3. Flagella, and Parasitic

Protists Examples of Animal-like Protista

Zooflagellates, Ciliates, Sporozoan

Fungi- Like

Act as decomposers Often have a slimy appearance/texture 3 types:

Plasmodial slime molds Cellular slime molds Water molds

Slime Mold

A team of scientists collected a unicellular, prokaryotic organism that lived in a volcanic hot spring and had lipids in its cell membrane that were not found in any other group of organisms. The scientists most likely classified the organism into which kingdom? Why would this organism not belong to kingdom Protista?

Kingdom Protista

Human uses Most algae are rich in vitamin C and iron Eaten in sushi and ice cream (the

thickening agent found in ice cream called algin is actually from brown algae.

When things go wrong

Some animal-like prostista cause serious diseases such as malaria, African sleeping-sickness
