🗑
|
||||
| unicellular | Consisting of only one cell.
🗑
|
||||
| algae | Plantlike protists.
🗑
|
||||
| facts about Kingdom Protista | ALL are eukaryotes MOST are unicellular; THIRD kindom to evolve EXTREMELY diverse, i.e. "Odds and Ends" or "Junk" Kingdom; 3 main categories; some are heterotrophs, some are autotrophs, some are both
🗑
|
||||
| What are the three main categories of Kingdom Protista? | Plant-like, animal-like, and fungus-like
🗑
|
||||
| What are the three types of protozoans | Sarcodines, ciliates, and flagellates.
🗑
|
||||
| What are the six types of algae? | Diatoms, dinoflagellates, euglenoids, red algae, green algae, and brown algae
🗑
|
||||
| mutualism | A type of symbiosis in which both partners benefit from living together.
🗑
|
||||
| symbiosis | A close relationship between two organisms in which at least one of the organisms benefits.
🗑
|
||||
| pigments | A chemical that produces color.
🗑
|
||||
| What are the types of funguslike protists? | Slime molds, water molds, and downy mildews.
🗑
|
||||
| Where do most water molds and downy mildews live? | Water and other moist places.
🗑
|
||||
| What type of protozoan feeds on the cells and body fluids of their host? | Parisite protozoans.
🗑
|
||||
| Do paramecia have more than one nucleus? | yes
🗑
|
||||
| What do amoeba use for movement? | pseudopods
🗑
|
||||
| What do paramecium use for movement? | cilia
🗑
|
||||
| What do flagellate use for movement? | flagella
🗑
|
||||
| Are euglena unicellular or multicellular? | unicellular
🗑
|
||||
| What are the two ways euglena get their food? | Photosynthesis and absorbing it.
🗑
|
||||
| Where would you find a euglena? | In quiet ponds or puddles.
🗑
|
||||
| What detects light in the euglena? | The eyespot.
🗑
|
||||
| What the function of the pellicle? | To help keep the cells shape.
🗑
|
||||
| How does the amoeba reproduce? | Usually by binary fission.
🗑
|
||||
| What is the eating process of the amoeba? | They extend a pseudopod on each side of the food particle. The two pseudopods then join together, trapping the particle inside.
🗑
|
||||
| What is the difference between the endoplasm and the ectoplasm? | The endoplasm is the darker cytoplasm that is found toward the interior of the protozoan while the ectoplasm is the clear part of the cytoplasm found near the cell membrane.
🗑
|
||||
| Where would you find an amoeba? | In ponds or puddles, sometimes humans.
🗑
|
||||
| Where can you find a paramecium? | In fresh and marine water containing bacteria, and decaying matter.
🗑
|
||||
| What is the function of the macronucleus? | To control most of the metabolic functions of the cell.
🗑
|
||||
| What is the function of the micronucleus? | It's involved primarily in reproductive and hereditary functions.
🗑
|
||||
| What are the names of the two nuclei paramecium have? | The macronucleus and the micronucleus.
🗑
|
||||
| What would happen if paramecium didn't have contractile vacuoles? | They would lyse (burst).
🗑
|
||||
| How does undigested food leave the paramecium? | It leaves through the anal pore.
🗑
|
||||
| facts about plant-like protists | some are unicellular, some are multicellular; autotrophs, though some can be heterotrophs under certain conditions and some are completely heterotrophic; BIG producers of oxygen; FYI green algae is closely related to plants (bothe have chloroplasts).

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
