Which single-celled organisms move using flagella?

• euglena and volvox

• volvox and amoeba

• euglena and paramecium

• paramecium and amoeba

What is the purpose of the eyespot in a euglena?

• to produce light that the euglena will use to create food through photosynthesis

• to sense light that the euglena will use to create food through photosynthesis

• to surround and trap particles that the euglena will eat as food

• to remove waste particles after the euglena has eaten food

How should an amoeba be classified?

• as an autotroph only, because the amoeba only uses photosynthesis to make food

• as a heterotroph only, because the amoeba only obtains food from its environment

• as both an autotroph and a heterotroph, because the amoeba uses photosynthesis to make food and also obtains food from its environment

• as neither an autotroph nor a heterotroph, because the amoeba neither uses photosynthesis to make food nor obtains food from its environment

How should an amoeba be classified?

• as an autotroph only, because the amoeba only uses photosynthesis to make food

• as a heterotroph only, because the amoeba only obtains food from its environment

• as both an autotroph and a heterotroph, because the amoeba uses photosynthesis to make food and also obtains food from its environment

• as neither an autotroph nor a heterotroph, because the amoeba neither uses photosynthesis to make food nor obtains food from its environment

Which two organisms contain chloroplasts and eyespots?

• amoeba and paramecium

• paramecium and volvox

• volvox and euglena

• euglena and amoeba

In which way are euglena and a volvox different?

• A euglena is an individual cell, while a volvox is a colony of cells.

• A euglena uses cilia to move, while a volvox uses flagella to move.

• A euglena can make its own food, while a volvox must capture its food.

• A euglena only reproduces sexually, while a volvox only reproduces asexually

Which single-celled organism lives in colonies and uses chloroplasts to make its own food?

• Amoeba

• Euglena

• Paramecium

• Volvox

The illustrations below are of a euglena, a paramecium, and an amoeba. How do these organisms compare?

• They use different structures for movement.

• They use different structures to control cell activity.

• They all make their own food by photosynthesis.

• They all have eyespots to sense sunlight.

What do these two organisms have in common?

• They are unicellular

• They cause diseases

• They live underground

• They are photosynthetic
