Epithelial cells play many very important roles in the human body. they are usually arranged in thin sheets of epithelial tissue and they cover internal and external surfaces. epithelial cells have many different functions, and their basic structure may be adapted to make them more efficient at their job. many epithelial cells are there to protect the tissues underneath from damage or infection.
"Specialized" means they have a very particular function in the body. For example, nerve cells only conduct nervous impulses, rod and cone cells only function in vision, gametes only function to pass on genetic information etc.
Permeable cells are cells that allow the movement of certain substances across their membrane. Examples include plant cells, red blood cells, and white blood cells. These cells have specialized structures that facilitate the movement of molecules in and out of the cell.

somethings are single celled. but some cells are multi celled like humans.
When each cell specializes in a certain task: some cells make fingernails, others become blood cells, brain cells, kidney cells, etc.

Some examples of specialized cells in cnidarians include cnidocytes (stinging cells) used for defense and capturing prey, sensory cells for detecting movement and light, and muscle cells for movement and contraction. Additionally, some cnidarians have specialized cells that secrete mucus or digestive enzymes for feeding.
Some examples of specialized cells in the body include red blood cells, which transport oxygen in the blood, neurons, which transmit electrical signals in the nervous system, and muscle cells, which contract to produce movement. Each type of specialized cell is uniquely adapted to its specific function in the body.
Some specialized cells may lose their ability to divide and reproduce, known as senescence, as they mature and carry out their specific functions. This loss of cell division capability helps maintain tissue structure and function but also limits the cells' ability to repair or regenerate. Examples include nerve cells and muscle cells.

Stem cells and leaf cells are two speacilized plant cells.
Examples of differentiated cells include red blood cells, nerve cells (neurons), muscle cells, skin cells, and liver cells. Each of these cell types has specific structures and functions that allow them to carry out their specialized roles in the body.
yes
Examples of cells that divide rapidly after maturity include skin cells, intestinal cells, and blood cells. Examples of cells that do not divide at all after maturity include neurons and cardiac muscle cells.
Permeable cells are cells that allow the movement of certain substances across their membrane. Examples include plant cells, red blood cells, and white blood cells. These cells have specialized structures that facilitate the movement of molecules in and out of the cell.
No. Most can except some specialized ones such as brain cells, red blood cells and gametes.
