1) The experiment worked because when the plant cells and the human cells were viewed in the microscope, they took on differentiating forms, enabling visual differentiation of the two forms of cells. The onion skin cell, an example of a plant cell, generally has a rigid, rectangular shape. The onion skin cells were positioned beside each other (length touching length, width touching width) and formed a checkered pattern. When observing the onion skin cell, we noticed that the cells took on a brick-like structure and within the cells, small dots (the nuclei) can be seen.When we first looked into the microscope, the microscope’s total magnification was 10X so there were about a hundred rows of rectangular cells (see diagram provided), but

organelles that were NOT visible but should have been in the cheek cell. mitochondria, lysosome, endoplasmic reticulum they are just not visible with the microscope you are using. They are very small organelles and cannot be visualized with traditional brightfield microscopy; you would need an electron microscope to be able to visualize them.
So, from the experiment conducted, we could know that the plant cells are much larger in size when compared to the animal cells, which are much smaller in size. This is because a plant cell could be seen under the low power microscope while an animal cell cannot be seen in a microscope in low power and medium power and must instead be viewed in high power.
-On low power microscopes and medium power microscopes it is not possible to view the animal cells directly since plant cells on average are about 15 times larger than the animal cells.
-The plant cells are also packed tightly in neat rows whilst the animal cell simply stands on it's own without being closely packed together. -The plant cells are larger than that of the animal cells because the vacuole, the food storage unit for the cell, is very large and almost takes most in the cytoplasm. This is because plant cells are able to produce their own energy all the time (this process is caused by a chemical found purely in plant cells called chlorophyll that is stored in parts of the cell called
