Protists and Fungi By: Ms. Avery 8 th grade Science

Intro Questions On p. 60 in your spiral notebook write and answer the following questions: 1. Categorize the kinds of living organisms into less than 8 groups. 2. Describe 2-3 characteristics for each of these groups (from question 1) that are true of all the organisms in the group. 3. How can you explain what a living organism is?

***How can you classify living organisms according to your answers?

Classification of Living Things Kingdom Kingdom Phylum Phylum Class Class Order Order Family Family Genus Genus Species Species  6 Kingdoms: Bacteria Archaea Protista Fungi Plantae Animalia

 If someone from outer space came to Earth and asked you how to tell if something is living or not living here on Earth, how would you explain it to them?

Common questions and misunderstandings  Most organisms including all animals and plants, use O2 to respire  The Kingdom Animalia includes: Insects, humans, mammals, fish, reptiles, birds, amphibians, arthropods (crabs, etc.)  There are mammals that live in the ocean (ex. Whales and dolphins)

All living organisms:  Grow  Respond to environment  Reproduce  Have organization (cell parts and functions) ****Have the ability to DIE

On p. 60 identify how you think each of the organisms move: 12121212 34343434

Terms to write at top of chart Terms to write at top of chart  Heterotrophs- eat (consumers)  Autotrophs- make own food (producers)

Movement Pics

Protozoa (animal-like Protists)  Unicellular and multicellular  Eukaryotic  Live in moist places  Movement: pseudopods (false feet), cilia (hair), flagellates (whip like)  Heterotrophs: decomposers or eat other organisms  Reproduction: binary fission or spores  Use vacuoles for digestion

Plant-like Protists  Unicellular and multicellular  Eukaryotic  Live in water  Movement: floating, flagella, cilia  Autotrophs: make own food  Reproduction: Binary Fission  Other: Euglena can change to heterotrophs, and Dinoflagellates can cause red sea poison

What can you infer from the pictures below?

Fungi-like Protists  Unicellular and multicellular  Eukaryotic  Live in moist places (land and water)  Can only move when first developing  Heterotroph-decomposers  Reproduction- spores  Info: Not fungi because can move at one point in their life

Other protists  Unicellular but become communable  Eukaryotic  Live in water  Movement: None when by themselves, but when together they can slide  Heterotrophs  Reproduction: Binary Fission

Protist Life Function Comparison (put on p. 66 of spiral notebook at top)  Euglena Autotrophs and heterotrophs Autotrophs and heterotrophs Flagella Flagella Plant-like Plant-like  Amoeba Pseudopods Pseudopods Animal-like Animal-like heterotrophs heterotrophs  Paramecium Cilia Oral groove (heterotrophs) Animal-like  Volvox Plant Kingdom Live in colonies flagella

 Euglena  Amoeba  Paramecium  Volvox

Fungi  Unicellular and multicellular  Eukaryotic  Live where it’s warm and moist (land and water)  Can’t move  Heterotrophs: eat dead things or are parasites  Reproduction: Spores (sexual and asexual), Budding (yeast)  Info.: Use hyphae to get food (except yeast), have cell wall and more than one nucleus

Helpful Fungi

Harmful Fungi

Closing questions (answer on p. 60 of spiral notebook)  How would you generate a plan to study protists and fungi further?  Rank the importance of what you learned the last few days (most important-1, least important-6) kingdoms/classification what a living organism is what protists are the four categories of protists what fungi is harmful vs. helpful fungi  What areas of what we learned the last few days, do you need more discussion on?
