Prokaryotes vs. Eukaryotes
Multiple Choice
In terms of cellular structure, which statement best describes whether eukaryotes have a cell wall?
A
Some eukaryotes (e.g., plants and fungi) have cell walls, while animal cells do not.
B
All eukaryotic cells have a cell wall made of peptidoglycan.
C
Only animal cells have a cell wall, primarily composed of cellulose.
D
No eukaryotic cells have a cell wall; only prokaryotes do.
Verified step by step guidance1
Step 1: Understand the definition of a cell wall and its general function. A cell wall is a rigid layer outside the plasma membrane that provides structural support and protection to the cell.
Step 2: Recall that eukaryotic cells are diverse and include plants, fungi, animals, and protists, each with different cellular structures.
Step 3: Identify which eukaryotes have cell walls. Plant cells have cell walls primarily made of cellulose, and fungal cells have cell walls made of chitin. Animal cells, however, do not have cell walls.
Step 4: Recognize that peptidoglycan is a component of bacterial (prokaryotic) cell walls, not eukaryotic cell walls, so the statement about all eukaryotic cells having peptidoglycan cell walls is incorrect.
Step 5: Conclude that the correct description is that some eukaryotes (plants and fungi) have cell walls, while animal cells do not.
