Accepted Answer

Synthesis of ribosomal RNA

Question 5

Which structure is found in plant cells but not in animal cells and is essential for photosynthesis?

Accepted Answer

Chloroplast

Question 6

A cell is observed to have a large central vacuole, a cell wall, and chloroplasts. Which of the following best describes the main function of the large central vacuole?

Accepted Answer

It stores water, nutrients, and waste products

Question 7

Which of the following organelles is directly involved in the breakdown of fatty acids and detoxification of harmful substances?

Peroxisome

Question 8

If a cell's smooth endoplasmic reticulum is damaged, which process would be most affected?

Accepted Answer

Synthesis of steroid hormones

Question 9

Which of the following best explains why plant cells can maintain a rigid structure while animal cells cannot?

Accepted Answer

Plant cells have a cell wall made of cellulose

Question 10

A researcher observes a cell with many cilia on its surface. What is the most likely function of these cilia?

Accepted Answer

To move the cell or move substances along the cell surface

Question 11

Which of the following is a function of the cytoskeleton in eukaryotic cells?

Accepted Answer

Provides mechanical support and helps maintain cell shape

Question 12

A cell is unable to transport proteins from the endoplasmic reticulum to the Golgi apparatus. Which cellular process would be most directly affected?

Accepted Answer

Protein modification and sorting

Question 13

Which of the following best describes the role of ribosomes in a eukaryotic cell?

Accepted Answer

They build proteins using instructions encoded in DNA

Question 14

A mutation in a plant cell prevents the formation of the cell wall. Which of the following would most likely occur as a result?

Accepted Answer

The cell would lose its rigid structure and be more susceptible to bursting in hypotonic solutions
