5.L.1.1 Unicellular and Multicellular Organisms

Front

What is a unicellular organism?

Back

A unicellular organism is an organism that consists of a single cell, capable of performing all life functions independently.

Front

What is a multicellular organism?

Back

A multicellular organism is an organism that is made up of multiple cells, which can specialize and perform different functions.

Front

What are the main characteristics of unicellular organisms?

Back

Unicellular organisms can complete all life functions with one cell, reproduce independently, and can be found in various environments.

Front

How do unicellular organisms meet their needs?

Back

Unicellular organisms meet their needs through processes that occur within their single cell, such as nutrient absorption and waste elimination.

Front

What is specialization in multicellular organisms?

Back

Specialization in multicellular organisms refers to the process where different cells take on specific roles to perform various functions, enhancing efficiency.

Front

Can unicellular organisms specialize?

Back

No, unicellular organisms cannot specialize like multicellular organisms; they perform all functions within one cell.

Front

What is an example of a unicellular organism?

Back

An example of a unicellular organism is a bacterium or a yeast.

Front

What is an example of a multicellular organism?

Back

An example of a multicellular organism is a human, tree, or dog.

Front

How do multicellular organisms obtain nutrients?

Back

Multicellular organisms typically have a transport system (like blood) to distribute nutrients to different cells.

Front

What is the role of a transport system in multicellular organisms?

Back

The transport system in multicellular organisms is responsible for moving nutrients, gases, and waste products throughout the body.
