The simple one-celled organism seen here moves by streaming its cytoplasm into “false feet “ or pseudopods. It can easily change shape to move and engulf its food. What is the name of this animal-like protists?

amoeba

paramecium

euglenoid

Diatoms

Both the euglena and paramecium seen here have___?

Question 12 options:

chlorophyll and are producers

projections that help them move

specialized cells to detect light.

a macronucleus and a micronucleus.

We use yeast, seen below, when we make bread. Some warm water and a little sugar and yeast are ready to divide through budding. Each yeast cell is identical to its parent cell. This is similar to regeneration in protists. This is a form of reproduction.

Question 13 options:

abiotic

asexual

genetic

sexual

Lichens, like the one shown in the picture below, are usually combinations of algae and fungi that have a beneficial “mutualisic” relationship know as ?

Question 14 options:

saprophytic

parasitic

symbiotic

autotrophic

Question 15 (1 point)
Fungi can be beneficial or destructive. One type of fungi, corn smut, attack grain plants like corn. What would likely happen to these crops when they are attacked by smut?

Question 15 options:

The crop yield is increased, because the fungi is symbiotic.

The plants stop reproducing

Results in huge crop loss, because the fungi is parasitic.

Question 17 (1 point)
Jimmy and Joanna were walking in their backyard and noticed a mushroom growing on the outside of a dead tree. Jimmy claimed that the mushroom was a plant, but Joanna said that it was not a plant, but a fungus.
In this case, what evidence BEST supports Joanna's claim?

Question 17 options:

The mushroom was a producer.

The mushroom was a autotroph.

The mushroom was a parasite.

The mushroom was a heterotroph.

Question 18 (1 point)
This is a unicellular protist called euglena. It lives in the water and swims around using the long flagella you see on one end. What do you, a complex multicellular human, have in common with the euglena?

Question 18 options:

They both can move.

Our cells are exactly the same.

Human cells move around using flagella.

The cells of multi cellular organisms must be in water also.

Question 19 (1 point)
A student performs an experiment to test the growth of bread mold. The student places four identical slices of white bread in individual plastic zip bags. Two of the slices are moistened with one pump of a spray bottle. The table describes the experiment and results.

What conclusion can be drawn from the experiment?

Question 19 options:

High moisture and low temperature encourage mold to grow.

Low moisture and high temperature encourage mold to grow.

Both low moisture and low temperature encourage mold to grow.

Both high moisture and high temperature encourage mold to grow

Question 20 (1 point)
How does the euglena differ from the paramecium?

Question 20 options:

Euglena are photosynthetic.

Paramecia use flagella to move.

Paramecia have an "eye spot" to detect light.

Euglena have both a macronucleus and a micronucleus

Question 21 (1 point)
Which organism is likely to live on the stump of a dead tree in a cool, moist, shady forest?

Question 21 options:

Diatoms

Euglena

Mushrooms

Paramecium

Question 22 (1 point)
Compare this fungus with the protist shown in the images below. How do they differ in the way they obtain nutrients?

Question 22 options:

Both organisms are autotrophs. The mushroom uses hyphae to get its nutrients and the amoeba uses the pseudopod instead.

Both organisms are consumers. The amoeba engulfs its food with it;s pseudopod, while the fungus absorbs food from the dead leaves using its hyphae.

The amoeba is a producer and obtains nutrients through photosynthesis; the fungus is a consumer and is decomposing leaf litter in the forest.
