Question

What can you see ? (long rows of rectangular cells in the unstained onion peel)

Answer 1

Long rows of rectangular cells are epithelial cells which perform the function of storage of nutrients.

Answer 2

We can see cell wall, cytoplasm, and nucleus under low magnification.

Explanation:

• When we see onion peel under a microscope, we find some rectangular structure or brick-like structure, these are onion cells. And within cells we can also find some dots, these are cell nuclei.  

• When we see the onion peel under low magnification (40X), we can see approximately 100 of onion cells.

• After increasing the magnification, we can see less number of cells, but the cells are more clear and larger than before.

• There is no space between two onion cell, they positioned beside each other and formed a net-like pattern.

• We can see cell wall, cytoplasm, and nucleus under low magnification.  Only under high quality microscope we can see individual cell organelle.
