Accepted Answer

Membrane-bound organelles such as the nucleus

Question 3

Which of the following best describes the main difference between animal and plant eukaryotic cells?

Accepted Answer

Plant cells contain chloroplasts and a large central vacuole, while animal cells do not.

Question 4

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

Question 7

Which evolutionary development is thought to have been crucial for the emergence of eukaryotic cells?

Accepted Answer

Development of membrane-bound organelles

Question 8

Which of the following structures is found in all eukaryotic cells but NOT in prokaryotic cells?

Accepted Answer

Nucleus

Question 9

A researcher observes a eukaryotic cell with a flagellum. What is the main function of this structure?

Accepted Answer

Cellular movement

Question 10

Which of the following best explains why eukaryotic cells can be much larger than prokaryotic cells?

Accepted Answer

Eukaryotic cells contain internal membranes that compartmentalize functions.

Question 11

Which of the following is a correct comparison between the genetic material of prokaryotes and eukaryotes?

Accepted Answer

Eukaryotes have their DNA enclosed within a nuclear envelope, while prokaryotes do not.

Question 12

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

Question 14

A eukaryotic cell is observed to have a large central vacuole. What is the primary function of this organelle?

Accepted Answer

Storage of water and maintenance of turgor pressure

Question 15

Which of the following best describes the evolutionary advantage of sexual reproduction in eukaryotes?

Accepted Answer

It increases genetic diversity, enhancing adaptability.

Question 16

Which of the following is a correct pairing of a eukaryotic organelle and its function?

Accepted Answer

Lysosome: digestion of macromolecules

Question 17

Which of the following is a key difference between the cell walls of plants and fungi?

Accepted Answer
