Protist and Fungi Notes: Chapter 19 & 20

Protists:  Junk-Drawer: Most diverse kingdom  Eukaryotes: mostly unicellular but some multicellular  Live in moist environments

Protists:  Move by using flagellum, cilia, pseudopods (“false feet”)  Classified as plant like, animal like, or fungus like

Animal – like protists: Protozoans:  Unicellular heterotrophs  Usually reproduce asexually (one parent makes identical offspring)  Ex: amoeba (move by pseudopodia), paramecium

Animal like protists  Helpful: trichonympha lives in gut of termite and helps digest wood, bottom of aquatic food chains  Harmful: cause diseases Ex: malaria (protist plasmodium Ex: malaria (protist plasmodium lives inside Anopheles mosquito) lives inside Anopheles mosquito) ex. African sleeping sickness: ex. African sleeping sickness: protist trypanosome transmitted protist trypanosome transmitted by tse tse fly by tse tse fly

Plant- like protists: Algae  Autotrophs: Carry out photosynthesis, contain chlorophyll  Many colors depending on pigment  Not plants because no roots, stems, or leaves but multicellular

Plant like protists  Helpful: produce more than 1/2 world's oxygen, foods (ice cream, salad dressing)  Harmful: cause algal blooms which kill aquatic animals, red tides (toxins that affect animals like shellfish and us when we eat them)

Fungus-like protists:  Heterotrophs: decompose organic material  Cause damage to crops (Ireland potato famine)  Ex: slime molds, downy mildews

2 minutes review with a partner 1. How do protists move? 2. How are protozoans like animals? 3. Why aren’t algae considered plants?

Fungi:  Eukaryotes: mostly multicellular, only unicellular fungi is yeast  Cell wall of chitin  Heterotrophs: decomposers—recycle nutrients so organisms can use them again; extracellular digestion

Fungi:  Threadlike filaments called hyphae form a mycelium which attaches to fruit or vegetative part of fungus draw picture!  Reproduction: –Asexual reproduction by producing spores or by budding; –Sexual reproduction

Fungi:  Examples: blue cheese, penicillin, athlete’s foot, mushrooms, food mold, baker’s yeast  Mycologists: scientists who study fungi

 Helpful: decomposition, food, medicines  Harmful: mold (allergies), diseases (ringworm, athlete's foot, wheat rust), poisonous mushrooms

Lichen  Fungus and algae living together in a mutualistic relationship (fungus protects algae from drying out, algae provides food)
