Protists + Algae Consequences Study Guide

Which organisms are classified in the protist kingdom?

• Organisms that fit the characteristics of plants, animals, or fungi

• Organisms that do not fit the characteristics of plants, animals, or fungi

• Only single-celled organisms

• Only multicellular organisms

What type of cells do protists have?

• Prokaryotic cells (without a nucleus)

• Eukaryotic cells (with a nucleus)

• No cells, as they are acellular

• Heterotrophic cells

What do pseudopods help amoebas to do?

• Move and trap food

• Reproduce

• Perform photosynthesis

• Breathe underwater

Which of the following is a characteristic of ciliates?

• They have pseudopods

• They have flagella

• They have cilia

• They are multicellular

What is the function of cilia in ciliates?

• To help the cell move and capture food

• To help the cell perform photosynthesis

• To help the cell reproduce

• To protect the cell from predators

What type of relationship do some flagellates have with other organisms?

• Predation

• Mutualism

• Parasitism

• Commensalism

Which of the following is an example of a parasite?

• Sharks and remoras

• Amoebas and pseudopods

• Giardia living in human intestines and making us sick

• Ciliates using cilia

What are algae?

• Animals that live in water

• Bacteria found in soil

• Plant-like protists

• Fungi that grow on trees

How do algae produce their food?

• Through chemosynthesis

• By consuming other organisms

• Using the sun's energy to make food

• Absorbing nutrients from the water

What is the role of algae in the atmosphere?

• They consume most of the oxygen

• They produce most of the atmospheric oxygen

• They deplete the ozone layer

• They have no significant role
