Which of the following statements regarding protozoa is false

Question 1

Which of the following statements regarding protozoa is false?

a. Protozoa are multicellular eukaryotes.

b. Some protozoa cause disease.

c. Protozoa are found in soil and water.

d. Parasitic protozoa are found in ticks and mosquitoes.

Question 2

Which of the following statements is false?

a. Most protists are aquatic.

b. Protists are eukaryotes.

c. Most protists are unicellular.

d. Protists have more complex cells than prokaryotes.

e. Photosynthetic protists are called protozoa.

Question 3

Which of the following statements regarding protozoa is FALSE?

Protozoa are animal-like Protists.

Protozoa are common in water and soil.

Protozoa are unicellular eukaryotes.

Protozoa have simple life cycles.

Answer to question 1

The following statement regarding protozoa is false: a) Protozoa are multicellular eukaryotes. Protozoa are unicellular eukaryotes, which means they are made of only one cell. They are microorganisms, which means they can only be seen under a microscope. Protozoa are found in aquatic environments and also in damp soil, and they have means of locomotion. This is important because protozoa must find and ingest their nutrition, which is the reason they are referred to as animal-like. They are unable to undergo photosynthesis like many other protists.

Answer to question 2

The following statement is false: e) Photosynthetic protists are called protozoa. This is not true, because protozoa are animal-like protists that are heterotrophs. Photosynthetic protists are autotrophs, making their own food and food for other organisms through photosynthesis. Protozoa are protists that move to find their food and must consume it instead of undergoing photosynthesis. Photosynthetic protists are algae, which are found in aquatic environments. They are the major producers within marine environments and in other aquatic ecosystems.

Answer to question 3

ANSWER:- d.)Protozoa have simple life cycles.

EXPLANATION:- Protozoa don’t have a simple life cycles instead they have different phases in their life cycle. Some protozoa have two-stage life cycles, with proliferative phases and resting cysts alternated. Some protozoa can endure difficult conditions as cysts, such as being exposed to extreme weather conditions or hazardous chemicals, or going without food, water, or oxygen for lengthy periods of time.

Protozoa comprise unicellular eukaryotes with animal-like characteristics. They have the ability to move and are heterotrophs, just like animals. That is, instead of creating their own food, they devour other people’s food.

Protozoa occur in a variety of shapes and sizes, from the amoeba, that can deform, to the Paramecium, which has a definite shape and complicated structure. They can be found in a range of wet locations, such as fresh water, ocean waters, and the soil.
