Question 3

Which structure is found in prokaryotic cells but NOT in eukaryotic cells?

Accepted Answer

Nucleoid

Question 4

A scientist observes a cell with a large central vacuole, chloroplasts, and a cell wall made of cellulose. What type of cell is this most likely to be?

Accepted Answer

Plant cell

Question 5

Which organelle is responsible for producing ATP through aerobic respiration and contains its own DNA?

Accepted Answer

Mitochondrion

Question 6

Which of the following best explains why cells are limited in size?

Accepted Answer

As cells get larger, their volume increases faster than their surface area.

Question 7

Which of the following is a function of the Golgi apparatus in eukaryotic cells?

Accepted Answer

Packaging and modifying proteins for secretion

Question 8

A cell is placed in a hypertonic solution. What will most likely happen to an animal cell in this environment?

Accepted Answer

It will shrivel due to water loss.

Question 9

Which of the following best describes the Fluid Mosaic Model of the cell membrane?

Accepted Answer

A flexible bilayer with proteins, cholesterol, and carbohydrates embedded throughout.

Question 10

Which process requires energy input from ATP to move molecules against their concentration gradient?

Accepted Answer

Active transport

Question 11

Which of the following is a real-life example of the importance of glycoproteins in the cell membrane?

Accepted Answer

Allowing cells to recognize and communicate with each other, such as in organ transplant compatibility

Question 12

Which of the following equations correctly represents the surface area to volume ratio for a cube-shaped cell with side length $$l$$?

Accepted Answer

$$	ext{Surface Area to Volume Ratio} = \frac{6l^2$}{l^3$}$$

Question 13

Which of the following is NOT a function of the cytoskeleton?

Accepted Answer

Accepted Answer

Hypotonic

Question 16

Which of the following is a key difference between prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells have a nucleus, while prokaryotic cells do not.

Question 17

Which of the following best explains why mitochondria and chloroplasts are considered evidence for the endosymbiotic theory?

Accepted Answer

They contain their own DNA and ribosomes, similar to prokaryotes.

Question 18

Which of the following best describes facilitated diffusion?
