Protists
| Question | Answer |
|---|---|
| What are the 3 groups of protists? | protozoans, algae & slime molds |
| Are all protists eukaryotes or prokaryotes? | eukaryotes |
| Is an amoeba an algae or protozoan? | protozoan |
| Is a paramecium an algae or protozoan? | protozoan |
| Are amoeba heterotrophs or autotrophs? | heterotrophs |
| How do amoeba move? | pseudopodia |
| How do amoeba get their food? | endocytosis (engulfs) |
| What do contractile vacuoles do for amoeba? | help to remove water from the interior |
| How do amoeba survive difficult environments (droughty)? | form cysts |
| What do amoeba have that allows them to move by pseudopodia? | have a flexible plasma membrane |
| How do amoeba reproduce? | asexually through binary fission |
| Are paramecium autotrophic or heterotrophic? | heterotrophic |
| How do paramecium take in their food? | by ingestion |
| How do paramecium move? | cilia |
| What do we call the hard outer covering of a paramecium? | the pellicle |
| Do paramecium have contractile vacuoles? | yes |
| How do paramecium sexually reproduce? | through conjugation |
| How do paramecium asexually reproduce? | through binary reproduction |
| Are euglena protozoans or algae? | algae |
| Are euglena heterotrophic or autotrophic? | both heterotrophic & autotrophic |
| How do euglena get their food? | they photosynthesize & absorb their food |
| How do euglena move about? | flagellum |
| What do we call the hard outer covering of a euglena? | the pellicle |
| Can euglena use the eyespot to 'see'? | No, the eyespot is used to detect light |
| Do euglena have contractile vacuoles? | yes |
| How do euglena reproduce? | asexually through binary fission |
| Why are euglena difficult to place in a kingdom? | they can photosynthesize like plants, but also absorb food like animals or fungi |
| Are volvox an algae or protozoan? | algae |
| Are volvox autotrophic or heterotrophic? | autotrophic |
| How do volvox move about? | individual cells of sphere have flagella |
| Volvox are colonial. What does this mean? | Many cells live cooperatively together as a sphere |
| How do volvox get their food? | through photosynthesis |
| What term refers to organisms that have membrane-bound organelles such as a nucleus? | eukaryotes |
| What does it mean to be autotrophic? | to feed oneself, such as in photosynthesis of plants or cyanobacteria |
| What does it mean to be heterotrophic? | to consume your food, such as in ingestion by animals or absorption by fungi |
