Biology lab question: observing cells. Need someone really good at Biology.?

Today I have a lab, we discover about dry cork cells, as you know, they are dead, and dry, I have some labs question that i like you to check it out. 1/ What specific cell part was all that was left on the cork? cell wall. 2/ In 1665, Robert Hooke, an English scientist, reported an interesting observation while looking through a microscope at corrk. " I took a good clear piece of cork, and with a penknife sharpened as keen as razor, i cut a piece of it off, then examining it with a microscope, me thought I could perceive it to appear a little porous, much like a honeycomb, but that the pores were not regular."" A/ What were the honeycomb units at which Hooke was looking? the death plant cell. B/ What specific cell part was all that was left of the cork? cell wall. 3/ What carbonhydrate makes up this part? I think that would be "carbon". (I don't know this answer to this question i am just guessing, my teacher give me the hint that, something that can (or can't) digest, start with a C). Are cork cells part of a producer or a consumer? consumer. PLZ PLZ GUYS HELP ME CHECK IT. I NEED HELP THE MOST WITH NUMBER 3, HELP.

1. the answer to number 3 is cellulose.
2. Cork consists mainly of suberin, a waxy substance found in higher plants. It is named after the name of the Cork Oak (Quercus suber). It's function is to prevent water from entering the plant tissue. You can find more on suberin on wikipedia, at http://en.wikipedia.org/wiki/Suberin Good luck!
