| Question | Answer |
|---|---|
| What have been called the “jewels of the sea?” | diatoms |
| Protists are eukaryotes that cannot be classified as _____, _______, or _______ | animals, plants, fungi |
| Which traits are shared by all protists? | they both live in moist environments and are eukaryotes |
| What are the 3 categories that scientists divide protists into? | Animal-like Plant-like Fungus-like |
| Animal like protists are _________, and most are able to move from place to place to ______ _______. | heterotrophs, obtain food |
| What name is given to animal like protists? | protozoans |
| what are Pseudopods | -the word means false foot -they are temporary bulgdes of the cell and they them pseudopods to move and eat -they form when cytoplasm flows toward one direction and the rest of the organism follows -also known as sarcodines |
| what is Contractile vacuole? | a structure that collects the extra water and expels it from the cell |
| what is Cilia? | hair-like projections that help the ciliate move and collect food |
| What characteristics make the amoeba suited to life in either soil or water? | it can change shape and flow easily through different substances |
| What characteristics make the paramecium suited to living only in water? | the ciliate has two contractile vacuoles and the ciliate wont beas effective in soil (because they aren’t strong enough on their own) |
| what is Symbiosis? | a close relationship in which one of the Species benefit |
| what is Mutualism? | a close relationship where both of the species beneift |
| What protozoan causes malaria? | plasmodium |
| How are algae similar to plants? | they are both autotrophs |
| What traits of algae vary greatly? | color and size size- unicellular to colonies of thousands of cells color- green red brown yellow orange or black |
| How many cells does a euglena have? | one |
| What color pigments can brown algae contain? | green, yellow, brown, and orange |
| What do fungi and fungi like protists have in common? | they both are heterotrophs, have cell walls, and use spores to reproduce |
| Like fungi, fungus-like protists are ___________, have __________ and use ___________ to reproduce. | heterotrophs, cell walls, spores |
| What are the 3 types of funguslike protists? | slime molds water molds downy mildew |
| How have funguslike protists caused human deaths? | Water molds destroyed the irish potato crops causing starvation |
| List the four types of animal-like protists. What are they each called | 1. Protozoans with pseudopods (sarcodines) 2. Protozoans with cilia (ciliates) 3. Protozoans with flagella (flagellates) 4. Protozoans that are parasites (they have no name |
| How are these four types of protists similar to animals? How are they different? | they are both heterotrophs and most are able to move and obtain food. but unlike animals they are all unicellular |
| You observe an animal-like protist under the microscope. It has no hairlike or whiplike structures. It moves by forming temporary bulges of cytoplasm. How would you classify this protist? | they are called pseudopods and the only protozoan that can form them is the sarcodines. |
| In what way are diatoms, dinoflagellates, and other plantlike protists similar to plants? | they all are autrotrophs |
| Why is sunlight important to plantlike protists? | because they all are autotrophs and use the sun’s energy like plants |
| Would you classify euglena as an animal-like protist or as a plantlike protist? Explain. | both because they could be both autotrophs and heterotrophs |
