Cells have their different parts with different functions and properties.
The diversity of cells reflects their different functions in organisms.
No
they have different functions
Different cells are different in structure because of their different functions (e.g. plant cells have cell walls because they don't have bones). Also, cells have different functions because they work together with other cells to create a working system (e.g. the human body)
To perform different functions plant cells assume different shapes
They have different Histological functions.
Because they have different functions
Cells are different shapes and sizes because they have different functions. The functions dictate the shapes and sizes.
Tissues are made up of different cells which perform similar functions.
Different cells have different appearences because they have different functions. A good rule of thumb is the "form follows function" rule.
No, different types of human cells have unique shapes and structures based on their functions. Cheek cells are flat and irregularly shaped because they are protective epithelial cells. Other cells in the body, such as nerve cells or muscle cells, have different shapes that suit their specific roles.
