19 SECTION 19.3 REVIEW Give and example of each of the following: a single-celled, a colonial, and a multi-cellular plant-like protist. 2. Many plantlike protists, or algae, reproduce sexually when conditions are harsh. Why might this be beneficial for a species? 3. If a multi-cellular organism contains chlorophyll c but no silica, to which phylum does it likely belong? Many biologists argue that the euglenoids should be classified as an animal-like protist rather than a plantlike protist. Explain.

22 2. Plant –like protists (Algae).
All are producers….contain chlorophyll and can make their own food. Many “phytoplankton” are a huge food source for most aquatic animals 1. Euglena chloroplasts Freshwater algae flagella eyespot Reproduction by fission

23 2. Diatom Salt water algae Also called “brown algae”
Photosynthetic protist that has a hard outer covering that looks like ______________________. This material does not decay, and is very useful to other organisms’ diets. Shiny glass-like material This gritty material is used in cleaning products.

24 3. Kelp (Brown seaweed) Also called multi-cellular brown algae, and can be eaten for food. The only multi-cellular protist Kelp forest off the coast of California in Monterey bay

25 4. Dinoflagellates Photosynthetic algae that are also classified as red or brown algae. “red tide” Overpopulation can cause _______________ An overproduction of dinoflagellates can cause “pollution” of water. This can effect the quality of water and fish-life in that area. It is cause by a sudden change in water temperature that causes a dramatic increase in dinoflagellate reproduction.

26 Other green algae Volvox Spirogyra Live in colonies
known for their spiraling chloroplasts and grow to many centimeters long Spirogyra

27 3. Fungus-like protists Decomposers
Grow on decaying material, such as logs and leaves on the forest floor. * Unlike fungus kingdom because of their cell wall The Potato Famine in Ireland in 1840’s was caused by Phytophthora infestans, fungus-like protist.

28 SECTION 19.4 REVIEW In what ways are slime molds and water molds similar to fungi? 2. Describe how slime molds help other organisms within an ecosystem obtain nutrients. 3. Make a three-column chat comparing plasmodial slime molds, cellular slime molds, and water molds. Why doesn’t spraying water on slime molds work to destroy them?

Protists have many different ___________________. Protists can be classified into ______________________, ______________________, and ______________________ phyla. All protists are ______________________ organisms, most of which are _________________________. Most animal-like protists can __________________, but all need to take in __________________. They can reproduce by _________________, _________________, and/or _________________. Some protists are plantlike. They produce _____________________ to make their own ____________________. As a bi-product, they produce _____________________ as well. These protists are considered the primary __________ ______________ for other organisms. Some will have a _________________________ to help them move about. The protists classified as fungus-like protest include _______________________. They are _______________________ and live off of ______________________.
