Detailed explanation-1: -This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape.

Detailed explanation-2: -One of the fundamental differences between the plasma membrane and the cell wall is in the type of organisms that they are found. The cell wall is present only in plants and the cell membrane is present in every living organism including plants. Present only in plants and in some fungi, bacteria, algae.

Detailed explanation-3: -This is mostly made of cellulose, and it gives a tough covering on the outside of the cell membrane. It therefore gives plant cells a distinctive polygonal outline. The cell wall also prevents the plant cell from swelling or shrinking as much as an animal cell would if placed in different liquids.

Detailed explanation-4: -The nucleus of the elodea cells is not visible under a compound microscope for a combination of reasons, including the masking by chlorophyll, the position of the nucleus, and the contact between the thin cell membrane and the cell wall.
