Which of the following statements is true regarding the presence of cell walls in animal cells?
A
Animal cells do not have cell walls.
B
Animal cells have cell walls made of chitin.
C
Animal cells have cell walls made of cellulose.
D
Animal cells have cell walls made of peptidoglycan.
Verified step by step guidance1
Begin by understanding the basic structure of animal cells. Animal cells are eukaryotic cells that typically lack a cell wall, which is a rigid layer found outside the cell membrane in some organisms.
Compare the structural components of animal cells with those of plant cells and fungi. Plant cells have cell walls made of cellulose, while fungi have cell walls made of chitin.
Consider the structural components of bacterial cells. Bacteria have cell walls made of peptidoglycan, which is different from the components found in plant and fungal cell walls.
Review the function of cell walls in organisms that possess them. Cell walls provide structural support and protection, but animal cells rely on other structures like the cytoskeleton for support.
Conclude by confirming that animal cells do not have cell walls, distinguishing them from plants, fungi, and bacteria, which have cell walls made of cellulose, chitin, and peptidoglycan, respectively.
