In science class, Cindy and Jane are conducting an investigation on living things to find out what the difference is between unicellular and multicellular organisms. First, they use a microscope to observe different types of organisms. Next, they go to the library to do more research on the organisms they observed with the microscope. Afterward, Cindy and Jane reviewed the observations and data results they recorded to come to a conclusion to the question: What is the difference between a unicellular organism and a multicellular organism?

• Unicellular organisms do not respond to stimuli in the environment. Multicellular organisms do respond to stimuli in the environment.
• Unicellular organisms are producers and multicellular organisms are consumers.
• Unicellular organisms perform all functions for life with one cell. Multicellular organisms have many cells that work together to keep them alive.
• Unicellular organisms are heterotrophs and multicellular organisms are autotrophs.

What is the main difference between heterotrophs and autotrophs?

• Heterotrophs can make their own food, while autotrophs cannot
• Autotrophs can make their own food, while heterotrophs cannot
• Heterotrophs live on land, while autotrophs live in water
• Autotrophs are animals, while heterotrophs are plants

How do autotrophs typically obtain their energy?

• By eating other organisms
• Through photosynthesis
• By breaking down dead matter

Which is an example of how an organism can maintain homeostasis?

• Changing color to blend in with surroundings.
• Growing larger to compete for resources.
