8.2 Cellular Structure

Front

What is the function of the cell membrane?

Back

The cell membrane forms a boundary between the cell and its surrounding environment and controls the passage of materials into and out of the cell.

Front

What would happen to a cell if many of its ribosomes were destroyed?

Back

The cell would not be able to make proteins.

Front

Where are proteins assembled in a cell?

Back

Proteins are assembled on ribosomes.

Front

What is a vacuole and what does it store?

Back

A vacuole is a fluid-filled sac for storage of materials; it stores food, water, and enzymes.

Front

What is the structure labeled #2 in a cellular diagram?

Back

Ribosome.

Front

What are ribosomes made of?

Back

Ribosomes are made of ribosomal RNA (rRNA) and proteins.

Front

What is the role of the nucleus in a cell?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the function of mitochondria?

Back

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

Front

What is the role of the endoplasmic reticulum (ER)?

Back

The endoplasmic reticulum is involved in the synthesis of proteins (rough ER) and lipids (smooth ER).
