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 / 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 / Three Classifications (eating habits) 1. Plant-like Protista / Produce their own food by photosynthesis. 2. Animal-like Protista / Heterotrophs 3.

/ 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 / 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 / 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 / Act as decomposers / Often have a slimy appearance/texture / 3 types: / Plasmodial slime molds / Cellular slime molds / Water molds

/ 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. / 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

Kingdom Fungi / To be a fungus you must: / Be a decomposer / Be Multi-cellular / Contain hyphae / Hyphae makes up fungi / To be a fungus you must: / Be a decomposer / Be Multi-cellular / Contain hyphae / Hyphae makes up fungi

Kingdom Fungi: Structure and Function / Multicellular- except for yeast (which is unicellular) / Composed of hyphae which are only one cell thick. / Multicellular fungi have tangled hyphae forming into a thick mass called mycelium. / FUNGI ARE DECOMPOSERS / Multicellular- except for yeast (which is unicellular) / Composed of hyphae which are only one cell thick. / Multicellular fungi have tangled hyphae forming into a thick mass called mycelium. / FUNGI ARE DECOMPOSERS

Kingdom Fungi: Reproduction / The top of the mushroom is actual called the fruiting body. / Fruiting body is the reproductive structure / The top of the mushroom is actual called the fruiting body. / Fruiting body is the reproductive structure

/ Most fungi are reproduce sexually and asexually. / HOW? / Sexual / When mating the two hyphae meet and fuse, bringing the plus and minus together in the same cell. / Also through the spreading of spores / Asexually / portion of the fungus breaks off and begins to grow on it’s own. / Most fungi are reproduce sexually and asexually. / HOW? / Sexual / When mating the two hyphae meet and fuse, bringing the plus and minus together in the same cell. / Also through the spreading of spores / Asexually / portion of the fungus breaks off and begins to grow on it’s own.

Kingdom Fungi: How They Spread / Fungi spread so easily because their spores are almost weightless and can reproduce in any area with the right amount of moisture and food.

Symbiotic Relationships / Parasitic- fungi can cause serious diseases in plants and animals. / Examples: Athletes Foot, Cordyceps, Corn Smut, etc. / Parasitic- fungi can cause serious diseases in plants and animals. / Examples: Athletes Foot, Cordyceps, Corn Smut, etc. / Mutualistic- fungi can form relationships that benefit other organisms. / Example: Lichens and mycorrhizae
