What are parasites?
Cells that do not move on their own. They live in or on other organisms.
What is the function of chlorophyll?
Chlorophyll helps plants, and plantlike protists, make food, susing the Sun's energy.
What is pseudopod?
A pseudopod is cellular movement that is involved in feeding.
What type of cell structure are most algae?
Most kinds of algae are single-celled.
What is at the base of the ocean food chain?
What are many plantlike protists called?
How do most protists reproduce?
Most protists reproduce by fission.
Give an example of a protozoan and tell how it operates.
An amoeba is a protozoan. Amoebas move by pushing out its cytoplasm and forming pseudopods. Amoebas also use their pseudopods to capture food. an amoeba completely surrounds the food and ingests it. Once inside the amoeba, the food is digested and used for energy.
