Answer 2

Answer:

There is no difference between the cells of two onion bulbs in terms of shape and size.

Explanation:

The peels (epidermis) are removed from a large and a small onion bulb. Then, both are immediately immersed in the water to prevent drying and folding of the peels. The temporary mounts of the onion peels are prepared to observe under the microscope.

Observation - A large number of regularly shaped cells with nuclei and vacuoles lying side by side were observed under the microscopes in both of the slides. The shape and size of the cells in both the peels are the same.

These cells are the building blocks of the onion bulb and have the same structural formation irrespective of the different sizes of onion bulbs.
