Astudent viewing a cell with a microscope observes a cell wall, a cell membrane, and a nucleus. the presence of these structures indicates that the student is looking at a cell a) rabbit b)carrot c)worm d)fly

The cell that the student observes contains a cell wall, which means it must be a plant cell or a fungal cell, as animal cells do not contain cell walls. Three of the options happen to be animals (rabbit, worm, and fly) and one a plant (carrot), so given the above information we know that the answer must be option B - carrot.

I also believe that the answer is B)carrot

Reason: Well first of, the cell has a cell wall. Once a cell wall is presents that immediately shows that the cell is of a plant type(or fungus).

Why the other answers are wrong: A rabbit, worm, are fly are animals so that means that they have animal cells. Animal cells do not have/contain cell walls but, they do contain a cell membrane and a nucleus.
