1.The large plant-like organism in the picture is a giant kelp, a type of protist called a brown algae. What role does the kelp play in this ecosystem? 2.How might the loss of this kelp affect the ecosystem?
TODAY’S OBJECTIVE: Be able to identify characteristics of the Kingdom Protista and Kingdom Fungi
Today we are going to look in more detail at two Kingdoms: Protista and Fungi
Microscopic Eukaryotic cells Most are single-celled Some are multi-cellular Live in moist areas Protista REVIEW: Why is Kingdom Protista referred to as the “junk drawer”?
Protista What are the three types of protista? Fungus-like SLIME MOLDS AND MILDEW Plant-like ALGAE Animal-like PROTOZOA HETEROTROPHS MOVEMENT AUTOTROPHIC PIGMENTS STRUCTURE DECOMPOSER REVIEW:
Section 19.1 Summary – pages 503-509 Fungus-like Protists Like fungus, they are decomposers and have a very similar body structure. Unlike fungus, these protista can move at some point in their life AND their cell walls are not made of chitin (a carb). Mildew Slime mold Water mold
Section 19.1 Summary – pages 503-509 Plant-like Protists Like plants, they have photosynthetic pigments and are autotrophs. Unlike plants, the plant-like protists do not have organs such as roots, stems and leaves. Diatoms Green Algae Red Algae Unicellular algae produce much of the oxygen in Earth’s atmosphere and are the basis of aquatic food chains.
We are going to concentrate on the animal-like protozoa today, and also try to find and identify some under the microscope. Like animals, protozoans can move around and they consume food for energy (heterotrophs). Unlike animals, protozoans are unicellular. Animal-like Protists
AMOEBAS Four Types of Protozoa Animal-like Protists Amoebas have no cell wall and form pseudopodia to move and feed. 1.
FLAGELLATES Animal-like Protists 2. Use a flagella to whip around Usually live inside of another organism Some cause disease like African sleeping sickness. High Fever, Headaches Eventually moves into the CNS Bouts of slumber and insomnia Fatal if not treated early
CILIATES Animal-like Protists Have little hair-like projections called cilia that help it move, get food, and sense the environment. 3.
SPOROZOANS Animal-like Protists Reproduce by making spores Internal parasites that cause disease, such as malaria Symptoms are fever, anemia, convulsions…and in severe cases- coma and death 4. A spore is a reproductive cell that forms without fertilization and produces a new organism.
Microscopic/Macroscopic Eukaryotic cells Most are multi-celled Some are uni-cellular Heterotrophs Live in moist, warm areas FUNGI REVIEW:
Section 20.1 Summary – pages 529-534 Fungi used to be classified in the plant kingdom because, like plants, many fungi grow anchored in soil and have cell walls. FUNGI The basic structural units of multicellular fungi are their threadlike filaments called hyphae, which develop from fungal spores. Some hyphae anchor the fungus, some invade the food source, and others form fungal reproductive structures.
