However, this is a simplification! Plant cells can be quite diverse in shape depending on their function and location in the plant. For example:

* Parenchyma cells, the most common type, are roughly spherical or oval.

* Collenchyma cells are elongated and provide support, giving them a more rectangular or elongated shape.

* Sclerenchyma cells are very thick-walled and can be star-shaped, fiber-like, or even have branching structures.

Ultimately, while the basic shape of a plant cell is rectangular or cubical, the exact form can vary greatly depending on the cell's function.
