protists

What is an autotroph?

An organism that produces its own food from inorganic sources, like plants.

Which protists are autotrophs?

Euglenas and volvoxes.

What is a heterotroph?

An organism that does not produce its own food and gets energy from other organisms.

Which protists are heterotrophs?

Parameciums and amoebas.

What is a pseudopod?

A foot-like structure of a protist that allows movement and feeding.

Which protists use pseudopods?

Amoebas.

What is chlorophyll?

The green pigment that plants use to make food during photosynthesis.

Which protists use chlorophyll?

Volvox and euglena.

How is cilia different from flagella?

Cilia are shorter and move in waves, while flagella are longer and move like a whip.

Which protists use cilia?

Paramecium.

Which protists use flagella?

Volvox and euglenas.

What is a eukaryote?

A cell with a nucleus and compartments that perform specific functions.

Which protists are eukaryotic?

All protists.

What is a prokaryote?

An organism that lacks a nucleus and compartments.

Which protists are prokaryotic?

None.

What is the process of making food using chloroplasts and sunlight called?

Photosynthesis.

If a protist is green, does that make it a plant?

No, a protist is its own organism.

How does having an eyespot help the euglena stay alive?

It allows it to find areas of light for photosynthesis.

Are protists eukaryotes or prokaryotes?

Eukaryotes, they have a nucleus.

How does the contractile vacuole help a protist stay alive?

It collects and removes excess water.

How do a protist's water vacuole and food vacuole help it survive?

The food vacuole helps digest and absorb nutrients.

How is the volvox different from other protists?

It is colonial and swims in a group with two flagella.

If the volvox did not have chloroplasts, how would this affect its survival?

It would not survive as it needs chloroplasts for nutrients.

If the amoeba did not have pseudopods, how would this affect its survival?

It would not be able to move or eat, making survival impossible.
