Question

Lignin and cellulose provide rigidity to the cell walls of plants. But in most fungi, chitin performs this role. Why is it logical that most fungi don't have lignin or cellulose in their cell walls?

Accepted Answer

Hi everyone. Let's look at our next question which the following makes up the fungal cell wall. Let's look through our answer choices. Choice A says lignin, lignin is a component of plant cell walls, especially in bark and would where it gives rigidity. So that is not our answer choice B is cellulose cellulose as we might recall. Makes up plant cell walls. So not our answer here. Choice E. Is kitten. And that is our answer. Chitin is a polymer of modified beta glucose sub units and that does make up the fungal cell wall and then finally we have choice D. Pepto glide. Can this makes up the cell walls of most bacteria? So that's why that's not our answer choice. So again, which of the following makes it the fungal cell wall choice. See titan. See you in the next video.
