nucleus

Plant cells are not necessarily square, but they due tend to have distinct edges and be somewhat rectangular. This structure is caused by the cell wall which is very rigid and therefore forces the cell to have a defined shape.

23.) Lysosomes -

Lysosomes are composed of lipids and proteins, with a single membrane covering the internal enzymes to prevent the lysosome from digesting the cell itself.
