Question

can you answer these
A microbiologist is in the process of classifying a newly discovered organism. Its characteristics include:

· eukaryotic
· multicellular
· reproduces by spores
· motile in some stage of its life cycle
· decomposer

Which type of organism is it most likely to be?
club fungus
fungus-like protist
plant-like protist
sac fungus

What is the main function of a fungus’s hyphae?
absorption of nutrients
movement in water
predator protection
photosynthesis

Which would least likely be seen on an information pamphlet for red tide?
People tend to stay out of the water in the area of a red tide.
People are warned to avoid eating shrimp and lobster.
People are making an effort to protect coastal areas from pollution.
People with respiratory conditions may be affected.

Why is a protozoan considered animal-like?
It is a heterotroph.
It is multicellular.
It has a flagellum.
It has a cell wall.

When you use toothpaste, part of a protist is helping to smooth and clean your teeth. Which part of the protist and type of protist are most likely responsible for this benefit to humans?
cell walls; plant-like
flagellum; plant-like
spores; fungus-like
cilia; animal-like

Answer 1

1) fungus-like protist
- Fits: eukaryotic, multicellular, spore reproduction, motile stage (e.g., slime molds/water molds), decomposer.

2) absorption of nutrients
- Hyphae increase surface area and secrete enzymes to absorb nutrients.

3) People are making an effort to protect coastal areas from pollution.
- Pamphlets focus on warnings and health/consumption advisories; community conservation actions are less likely to be a primary pamphlet message.

4) It is a heterotroph.
- Protozoa ingest/absorb food rather than photosynthesize, like animals.

5) cell walls; plant-like
- Diatoms (plant-like protists) have silica cell walls used as mild abrasive/cleaning agents in toothpaste.
