Ascientist is comparing the outer layer of an onion cell to the outer layer ofna human skin cell. what is unique about the outer layeer of the onion cell compared to the skin cell. a. it contains proteins. b. it contains cellulose. c. it contains carbohydrates. d. it is selectively permeable

The correct answer is B: it contains cellulose.

Explanation:

Looking at all of the options for this answer, we know that both plant and animal cells contain a, c, and d (a selectively permeable membrane). That leaves us with b: cellulose. Cellulose is found ONLY in plants, and it is what gives them their structure. That is what is different from the onion (the plant cell) and the human skin (the animal cell). Let me know if this helps!
