Multiple Choice
Which of the following is an example of a prokaryotic cell?
A
A yeast cell
B
A human red blood cell
C
Escherichia coli (a bacterium)
D
A plant leaf mesophyll cell
Verified step by step guidance1
Step 1: Understand the difference between prokaryotic and eukaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have these features.
Step 2: Identify the characteristics of each option. Yeast cells, human red blood cells, and plant leaf mesophyll cells are all eukaryotic because they have a nucleus and organelles.
Step 3: Recognize that Escherichia coli is a bacterium, and bacteria are classified as prokaryotes because they do not have a nucleus or membrane-bound organelles.
Step 4: Conclude that among the options, Escherichia coli is the example of a prokaryotic cell.
Step 5: Remember that prokaryotic cells are generally smaller and simpler in structure compared to eukaryotic cells, which helps in identifying them.
