because a body is more efficient when it has specialized cells. The human body for instance has many types of specialized cells. the neurons (brain cells) perform a different function then skin cells. This specialization allows for complex life beyond single celled organisms because not every cell has to catch nutrients from the environment. Since very few of your cells actually work on absorbing nutrients from the environment, they can focus on other tasks, such as holding your shape (bones), thinking (brain cells), etc.
Specialized cells are dependent on other specialized cells because they need to live off other cells otherwise specialized cells wouldn't exist. Every specialized cell is designed to carry out a special function, there for we need a bunch of different specialized cells for the entire organism to survive.
as cells differentiate, they become different form one another. They also form groups made of other, similarly specialized cells. These groups then form tissue and organs.
it's true
when cells become specialized, they take up a particular function in the body, and they adapt their shape and function according to it i.e. a white blood cell is specialized as it is full of enzymes that fight off harmful bacteria. another is a nerve cell, designed for transferring "messages" through the body
White blood cells protect the body by fighting off or killing the bacteria, pathogen or microorganism that caused it. They do this by ingesting harmful foreign bodies.

Yes. Our body will have new cells to replace. (Not sure about answer)Yes they do.Dead cells is what hair and finger nails are made off.

white blood cells
The immune system has special cells that help the body to fight off any invaders.
Yes. An apple is made of cells.

Tiny human cells
Cells become specialized through differentiation, which means that all cells within our body turn on and off the genes that are producing different proteins, thus making them responsible for specific functions.
