Accepted Answer

Protein synthesis

Question 4

Which feature is unique to prokaryotic cells as shown in the diagram?

Accepted Answer

Flagellum

Question 5

If a scientist observes a cell with a nucleoid region but no membrane-bound nucleus, which type of cell is it most likely to be?

Accepted Answer

Prokaryotic cell

Question 6

Which of the following equations best represents the process of cellular respiration that occurs in the mitochondria of eukaryotic cells?

Accepted Answer

$C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + ATP$

Question 7

Which of the following statements about the plasma membrane is correct based on the diagram and your knowledge?

Accepted Answer

It regulates the movement of substances into and out of the cell.

Question 8

A student observes a cell with mitochondria, a nucleus, and endoplasmic reticulum. According to the diagram, this cell is most likely:

Accepted Answer

A eukaryotic cell

Question 9

Which of the following best explains why prokaryotic cells are generally smaller than eukaryotic cells?

Accepted Answer

Prokaryotic cells do not contain membrane-bound organelles, limiting their complexity and size.

Question 10

Which of the following is a correct sequence of biological organization from smallest to largest, as illustrated by the diagram and study materials?

Accepted Answer

Organelle → Cell → Tissue → Organ

Question 11

Which of the following is a function of the cell wall in prokaryotic cells as shown in the diagram?

Accepted Answer

Providing structural support and shape

Question 12

If a mutation prevented the formation of ribosomes in a cell, what would be the most immediate consequence?

Accepted Answer

The cell would be unable to synthesize proteins.

Question 13

Which of the following best describes the function of the nucleoid region in prokaryotic cells?

Accepted Answer

It contains the cell's genetic material.

Question 14

Which of the following is NOT a function of the structures labeled in the eukaryotic cell diagram?

Accepted Answer

Photosynthesis in the nucleoid

Question 15

Which of the following best explains why antibiotics can target prokaryotic cells without harming eukaryotic cells?

Accepted Answer

Prokaryotic cells have unique cell wall structures not found in eukaryotic cells.
