Cell Structure and Function Concepts

What is the primary difference between unicellular and multicellular organisms?

• Unicellular organisms have a nucleus, while multicellular organisms do not.

• Multicellular organisms have a cell membrane, while unicellular organisms do not.

• Unicellular organisms are made of one cell, and multicellular organisms are made of many cells.

• Multicellular organisms can divide, but unicellular organisms cannot.

Which of the following is NOT a part of the Modern Cell Theory?

• The cell is the smallest living unit in all organisms.

• All living things are made of cells.

• All cells come from other pre-existing cells.

• Cells are always multicellular.

What is a key difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus, while eukaryotic cells do not.

• Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.

• Prokaryotic cells have cytoplasm, while eukaryotic cells do not.

• Eukaryotic cells have ribosomes, while prokaryotic cells do not.

What is the main job of ribosomes in a cell?

• To control what goes in and out of the cell.

• To provide support for the cell.

• To make proteins.

• To store genetic information.

Which part of a eukaryotic cell acts as the "cell headquarters" and stores genetic material?

• Mitochondria

• Nucleus

• Nucleus

• Endoplasmic Reticulum

• Chloroplast

What is the main function of mitochondria in a cell?

• Packaging and sorting proteins

• Producing energy (ATP)

• Detoxifying harmful substances
