What is the difference between cells in onion peel and cells in spinach?

The cells that are present in both the samples are plant cells but the main and the most important difference that is seen when both the cells are compared are the presence of the number of the chloroplast cells that are present in both the cells as you might have seen that the onion peel is not green in colour and usually the plant gets its green colour because of the chloroplast cells, thus the number of these cells will be very less in onion peel where as the sample cells from spinach will have very large number of chloroplast cells when compared to the onion peels because spinach is. leafy green vegetable and the leaves have the maximum number of chlorophyll cells.
