All cells ARE NOT the same shape. Cells can be of diverse structures.
Because they have different functions
Cells are different shapes and sizes because they have different functions. The functions dictate the shapes and sizes.
Cells have different shapes and sizes to fulfill specific functions within an organism. The shape and size of a cell determine its ability to perform certain tasks, such as movement, absorption, or secretion. This diversity allows for the efficient functioning of different tissues and organs in multicellular organisms.
Cells in different tissues have different shapes and sizes because they are specialized to perform specific functions. For example, muscle cells are elongated to generate force and movement, while red blood cells are small and rounded to efficiently transport oxygen. The shape and size of cells are dictated by their specific roles and requirements within the tissue they belong to.
With cells, the rule of thumb is, structure defines function. Different cells throughout the body perform different functions. To perform these functions, they need different shapes. They all have the same DNA, but different "blueprints" are activated depending on where they are in the body.

Hexagon,octagon,nonagon,are a few figures with the same shape but may have a different size. * * * * * Two or more figures of the same shape but with different sizes are said to be similar.
They are 'similar' figures.
