Characteristics of an organism:
1. Made of many cells
2. Each cell has a nucleus
3. Eats other organisms
4. Can move itself around
Which word would describe this organism?

• Autotrophic
• Prokaryotic
• Immotile
• Multicellular

Characteristics of an organism:
1. Cells have nuclei
2. Cannot move itself
3. Makes its own food
4. Made of many cells
Which word would NOT describe this organism?

• Multicellular
• Autotrophic
• Prokaryotic
• Immotile

Scientists discover a single-celled organism in pond water that has a nucleus. This organism can move using a flagellum. Which pair of words can be used to describe this organism?

• Prokaryotic and unicellular
• Prokaryotic and motile
• Eukaryotic and multicellular
• Eukaryotic and motile

Characteristics of an organism:
1. Cannot move itself around
2. Absorbs food particles
3. Made of many cells
4. Cells have nuclei
Which word cannot be used to describe this organism?

• Eukaryotic
• Heterotrophic
• Immotile
• Unicellular

Characteristics of an organism:
1. Has a nucleus
2. Made of one cell
3. Has cilia for movement
4. Makes its own food
Which word would describe this organism?

• Heterotrophic
• Prokaryotic
• Multicellular
• Motile

Scientists are studying an organism that can make its own food. It is made of trillions of cells, and each cell has its own nucleus. Which pair of words could be used to describe this organism?

• Autotrophic and prokaryotic
• Autotrophic and eukaryotic
• Heterotrophic and eukaryotic
• Heterotrophic and multicellular

Animals are considered highly motile organisms. This is because animals-

• can make their own food
• can move themselves around
• are composed of a single cell
• do not contain nuclei in their cells

Why are plants considered autotrophic organisms?

• They contain many cells
• Their cells contain nuclei
• They can produce their own food
• They cannot freely move on their own

Protists are a group of mostly single-celled organisms. All protists are considered eukaryotic. What makes protists eukaryotic?

• All protists can make their own food
• All protists contain a cell nucleus
• Every protist is able to move itself around
• Every protist is classifies as unicellular

Each cell in the organism has a nucleus.

• Prokaryotic
• Eukaryotic
