Cell A has a large, dark nucleolus surrounded by greyish material (chromatin) that is enclosed within the nuclear membrane. A cell wall makes a box around each cell and the plasma membrane would be located just inside this box, though we cannot easily see it.Onion cell and cheek cell both are eukaryotic cells as they have a distinct nucleus. An onion cell is a plant cell that has an outermost rigid cell wall and a large vacuole. They appear brick-like in shape. On the other hand, a human cheek cell is an animal cell having a rounded structure but lacking a cell wall. So, the correct answer is 'False'.
