Unit 3: Cell Structure and Function Practice

Front

What do prokaryotic and eukaryotic cells have in common?

Back

Both prokaryotic and eukaryotic cells contain DNA.

Front

What structure provides rigidity and support in plant cells?

Back

The cell wall provides rigidity and support in plant cells.

Front

What is the primary function of the cell membrane?

Back

The cell membrane regulates the passage of substances in and out of the cell.

Front

What is true about the cells of multicellular organisms?

Back

The cells of multicellular organisms are specialized to carry out unique functions.

Front

What must unicellular organisms do?

Back

Unicellular organisms must perform all life functions within a single cell.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have them.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What role does the nucleus play in eukaryotic cells?

Back

The nucleus houses the cell's DNA and controls cellular activities.

Front

What is the function of mitochondria?

Back

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.

Front

What is the purpose of the endoplasmic reticulum?

Back
