Question 1

Which of the following statements best describes a unique feature of eukaryotic cells compared to prokaryotic cells?

Accepted Answer

Eukaryotic cells contain a nucleus enclosed by a double membrane, while prokaryotic cells lack a true nucleus.

Question 2

Which organelle is responsible for ATP production through aerobic cellular respiration in eukaryotic cells?

Accepted Answer

Mitochondrion

Question 3

A scientist observes a cell with a '9+2' arrangement of microtubules in its locomotory structures. What is the most likely function of these structures?

Accepted Answer

Movement of the cell or movement of substances along the cell surface

Question 4

Which of the following best describes the main difference between the cell walls of bacteria and eukaryotic microorganisms such as fungi and algae?

Accepted Answer

Bacterial cell walls contain peptidoglycan, while eukaryotic cell walls do not.

Question 5

Which of the following is a function of the eukaryotic glycocalyx?

Accepted Answer

Protection, cell recognition, and adhesion

Question 6

Which process involves the uptake of large solid particles by a eukaryotic cell through the plasma membrane?

Accepted Answer

Phagocytosis

Question 7

Which of the following best explains why eukaryotic plasma membranes are more flexible than prokaryotic plasma membranes?

Accepted Answer

Eukaryotic membranes contain sterols such as cholesterol.

Question 8

A cell is observed to have ribosomes attached to its endoplasmic reticulum. What is the primary function of this organelle?

Accepted Answer

Synthesis of proteins for secretion or membrane insertion

Question 9

Which of the following is NOT a function of the Golgi apparatus in eukaryotic cells?

Question 11

Which of the following best describes the function of peroxisomes in eukaryotic cells?

Accepted Answer

Breakdown of hydrogen peroxide and lipid biosynthesis

Question 12

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

Question 16

Which of the following is the main function of the nucleolus in a eukaryotic cell?

Accepted Answer

Ribosomal RNA synthesis and ribosome assembly

Question 17

Which of the following best describes the process of receptor-mediated endocytosis?

Accepted Answer
