AP Biology Cell Structure and Function

Front

What is the function of the smooth endoplasmic reticulum?

Back

The smooth endoplasmic reticulum is responsible for synthesizing lipid materials and breaking down toxins.

Front

Which of the following is not part of a prokaryotic cell: nucleolus, ribosome, or plasma membrane?

Back

Nucleolus is not part of a prokaryotic cell.

Front

What is the structure that serves as the boundary of the cell and is composed of phospholipids?

Back

The cell membrane.

Front

What are vacuoles and what do they store?

Back

Vacuoles are fluid-filled sacs that store water, food, wastes, salts, or pigments.

Front

Why is the surface area to volume ratio important for cells?

Back

A large surface area to volume ratio is crucial for cells to ensure that materials can cross the membrane quickly enough.

Front

What is the primary function of the rough endoplasmic reticulum?

Back

The rough endoplasmic reticulum is primarily involved in the synthesis of proteins.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

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

Front

What is the function of lysosomes?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris.

Front

What is the significance of the cell membrane's phospholipid bilayer structure?

Back

The phospholipid bilayer structure of the cell membrane provides a barrier that is selectively permeable, allowing certain substances to enter or exit the cell.
