Question | Answer |
What are the three domains? | Eukarya, Archaea and Bacteria |
What are the five supergroups to classify protists? | Excavata, Chromeolavata, Rhizaria, Archaeaplastida, and Unikonta |
What are fungus-like protists? | Like fungi -heterotrophs, they must obtain food outside themselves. have cell walls and reproduce by forming spores. usually do not move, but a few develop movement at some point in their lives. Two major types are slime molds and water molds. |
plasmodium | mass of undistinguishable cells |
What does Physarum polycephalum do when env becomes unfav? | 1. from sclerotium
2.grow spore-bearing sporangiophores |
What are sclerotium? | irregular mass of hardened components that is resistant to desiccation |
What are sporangiophores? | grow sporagnia inside |
What are sporangia? | undergo meiosis and produce haploid spores |
How to fungus-like protists differ from fungi? | have cellulose in cell walls, produce flagellated reproductive cells(zoospores), |
What is hyphae? | network of branching tubules |
mycelium | mass of hyphal strands |
types of fung-like protists | slime and water molds |
animal -like protists | they can move, heterotrophs. eat things outside of themselves instead of producing their own food. Animal-like protists are very small, measuring only about 0.01–0.5mm. Animal-like protists include the flagellates, ciliates, and the sporozoans. |
types of animallike protists | amobea, euglenozoans, apicomplexans, ciliates |
amboea | pseudopods, two layers that move, no shape |
euglenozoans | whiplike flagella` |
apicomplexans | sporelike infections, lack flagella |
ciliates | have cilia, two nuclei |
plant-like protists | also called algae are a large and diverse group Some algae are tiny,unicellular, others large,multicellular. largest-seaweeds. photosynthesize, and are"simple" do not have leaves ,vascular tissue. are eukaryotic organisms. have a nucleus c,hloroplasts |
types | green algae,diatoma,, red algae, brown algae, dinoflagellates |
