Question | Answer |
What are the three protists groups? | proclucers, heterotrophs that move, and heterotrophs that can't move |
What protists are producers? | algae, seaweeds, red algae, green algae, brown algae, single-celled algae, diatoms, dinaoflagellates |
Where do algae live? what do they all have? | in water. chlorophyll |
red algae live where? what do they have? | deep in the tropical waters. chlorophyll, red pigment |
what does the red pigment in red algae do? | allows the algae to absorb the light in deep waters |
what is an example of red algae? | sebdenia |
where do green algae live? what do they have? | water, moist soil, melting snow, tree trunks, and inside other organisms. some live in groups called colonies |
what is an example of green algae? | volvox |
What are in euglenoids? | chloroplasts, nucleus, contractile vacuole, eyespot, and flagella (usually two), they are single-celled |
What is an eyespot? | it is not an eye it is something that senses light |
contractile vacuole? | holds excess water and removes it from the cell |
where do euglenoids live? | freshwater |
Heterotrophs that move usually are... | single-celled consumers or parasites |
heterotrophs are also known as... | protozoans |
amoebas where do they live? what do they have? | fresh and salt water and parasites in animals. contractile vacuole, psuedopodia |
what do shelled-amoeba have? | some have outershells like radiolarians |
what is an example of a shelled-amoeba with a snail-like shell? | foraminiferans |
where do zooflagellates live? | water and some are protists |
if the zooflagekllate is a protist they might live in... | mutualism |
mutualism | where one organism lives closely with another helping each other to live |
ciliates have what? | cilia |
cilia | hair like structures |
what is an example of ciliates? | paramecium |
what do paramecium have? | macronucleus, micronucleus, food vacuole, cilia, contractive vacuole, anal pore, and food passageway |
macronucleus | the larger nucleus that controls the functions of the cell |
micronucleus | smaller nucleus that passes genetic info to another paramecium during sexual reproduction |
what are water molds? | decomposers or parasites |
heterotrophs that can't move are.. | spore-forming protists |
parasite | absorbs nutrients from host |
can slime molds move? | during a certain phase of their life cycle they can move using psuedopodia. |
what do slime molds eat? | bacteria and yeast |
spores | small reproductive cells covered by a thick cell wall |
what can survive long periods of time without water or nutrients? | spores |
what kind of reproduction do protists have? | asexual and sexual |
binary fission | single celled protist divides into 2 |
multiple fission | make more than 2 offspring from one parent |
what uses sexual reproduction? | paramecia |
2 paramecia exchange DNA then they... | divide into 4 paramecia |
Can protist reproduce both ways? | yes, some alternate between generations while some depend on environment (like slime mold) |
