Question 1

Which of the following statements best describes the Fluid Mosaic Model of the plasma membrane?

Accepted Answer

It is a double layer of phospholipids with embedded proteins and carbohydrates, allowing selective permeability and flexibility.

Question 2

A cell is placed in a solution and water moves into the cell, causing it to swell. Which property of the plasma membrane is most directly responsible for this movement?

Accepted Answer

Selective permeability

Question 3

Which organelle is primarily responsible for producing ATP via aerobic respiration?

Accepted Answer

Mitochondrion

Question 4

A patient has a genetic disorder affecting the structure of their microtubules. Which cellular process is most likely to be impaired?

Accepted Answer

Cell division and chromosome distribution

Question 5

Which of the following best explains why skeletal muscle cells are multinucleate?

Accepted Answer

They require multiple nuclei to control the synthesis of large amounts of proteins needed for contraction.

Question 6

Which cellular extension is responsible for moving materials across the surface of respiratory cells?

Accepted Answer

Cilia

Question 7

During which phase of the cell cycle does DNA replication occur?

Accepted Answer
