PROTISTS AND FUNGI

Similarities and Differences in the Protist Kingdom All are eukaryotes (cells with nuclei). Live in moist surroundings. Unicellular or multicellular. Autotrophs, heterotrophs, or both. Some can move - others cannot.

3 categories of Protists: Animal-like Fungus-like Plant-like

Animal-like Protists (Protozoans) *Unicellular Heterotrophs *Four groups based on movement: those with flagella, cilia, pseudopods, and the ‘others’.

Protozoans with Pseudopods Pseudopods also called ‘false feet’ Cell membrane pushes in one direction & the cytoplasm flows into the bulge. This allows the protozoan to move, dragging the rest of the cell behind it.

EXAMPLE OF HOW PSEUDOPODS MOVE Pseudopod Movement EXAMPLE OF HOW PSEUDOPODS MOVE FLOW PUSH DRAG

Pseudopods & Feeding They can form pseudopods to surround & trap food. Then form a food vacuole to break down food in the cytoplasm.

Pseudopods Reproduce by mitosis Contractile vacuole - it collects extra H2O & expels it from cell Thin cell membrane No definite shape. Example - Amoeba

Protozoans with cilia Cilia - hairlike structures - help organisms move, get food and sense environment. Multicellular with 2 nuclei. 1 nuclei controls everyday functions 1 nuclei is for reproduction. Reproduce by mitosis or conjugation.

Ciliates Oral groove lined with cilia - moves H20 containing food into food vacuole at end of oral groove. Food vacuole breaks down food and sends through cell. Anal pore sends out waste. Example of protozoan w/ cilia: paramecium.

CILIA CONTRACTILE VACUOLE FOOD VACUOLE ORAL GROOVE FOOD VACUOLE ANAL PORE

Protozoans with flagella Organisms called zooflagellates Use long whiplike part called flagella to move. These usually live inside other organisms.

Other Protozoans Called sporozoans - parasites Feed on cells & body fluids of hosts Sporozoans like Plasmodium (causes malaria) have more than 1 host: mosquitoes and then humans

Funguslike Protists Like animals, they are heterotrophs Like plants, they have cell walls Reproduce by spores (tiny cells that can grow into a new organism) Not in fungi kingdom because they can move at one point in their lives. Example are water or slime molds.

Plantlike Protists Better known as algae Autotrophs Size: unicellular to very large Contain different pigments so they come in different colors. Euglena: special type of algae -when there is no sunlight they become heterotrophic.

Fungi Kingdom Eukaryotes Use spores to reproduce Heterotrophs that feed in a similar way Need warm, moist places to grow Examples: yeast, molds, mildew, and mushrooms

Fungi -Obtaining food Use a structure called hyphae to get their food. Except for yeast which are unicellular. Hyphae: threadlike, cytoplasm-filled tubes with nuclei Shape of fungi depends on how hyphae used. AND...

The fungal hyphae grows into food then secrete digestive chemicals into food & absorb it Stolons – horizontal hyphae Rhizoids- hyphae forming rootlike structures

Reproduction in Fungi Produce thousands of spores with a protective covering: carried by water and air. spores land in a warm, moist place they form more fungi AND...

Reproduction in Fungi When there is plenty of moisture, fungi reproduce asexually by releasing spores. When conditions are not good, they reproduce sexually.

Yeast are unicellular, they reproduce by budding Yeast are unicellular, they reproduce by budding. A well fed cell grows from the body of the mother cell and breaks off from the mother.

Four classifications of Fungi Threadlike - produce spores in their threadlike hyphae (ex. Bread mold) Saclike - produce spores in structures that look like sacs (ex. Yeast)

Club - produce spores in structures that look like clubs (ex Club - produce spores in structures that look like clubs (ex. Mushrooms) Imperfect - those that cannot reproduce sexually (ex. Penicillin)
