There are many examples of how cell shapes are suited to their function. Sperm cells are small and light so that they can move quickly toward the ovum, the ovum is large so that it can store energy for development and neurons are long to allow for connections to reach long lengths in order to send signals quickly.
what is the flattened cells important in protection, that fits together like tiles?
Epithelial cells have several functions. They line, protect, and form different glands. Epithelial cells have three shapes: flattened, cube, and elongated.
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.
(1) A nerve cells long extensions reach out in various directions to enable them to receive and transmit impulses. (2) Dead Skin Cells flat shape enables them to cover the surface of the body well.(Page 71 Holt Modern Biology Textbook)
No - they have very different shapes in order to perform their specific functions. Nerve cells are long with branched 'dendrites' at the end. There are many different blood cells, one of which - red blood cells - are almost circular with an indent in the middle.
Cells are different shapes and sizes because they have different functions. The functions dictate the shapes and sizes.
To perform different functions plant cells assume different shapes
Their different shapes help them to perform their various functions (jobs)
Specialized animal cells are cells found in animals that perform specific functions and only those specific functions. Examples include nerve cells, muscle cells and red blood cells.

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.
Red blood cells all look like red blood cells. White cells have different shapes mainly because they have different functions.
No - they have very different shapes in order to perform their specific functions. Nerve cells are long with branched 'dendrites' at the end. There are many different blood cells, one of which - red blood cells - are almost circular with an indent in the middle.
What is true of cells that have similar functions?
