What Does A Cell Do?

The cell is the building block that makes up living things. Everything that is alive is made of one or more cells. The simplest plants and animals consist of only one cell. Cells in more complicated living things work together. They are organized in groups, each other which has some special work to do for the plant or animal.

A tissue is a group of cells of a particular kind that does one particular type of work. For example, there is bone tissue, muscle tissue, or bark tissue. When tissues co-operate to perform a special task, such a group of tissues is called an "organ". An example of this is the human hand, which is composed of bone, muscle, nerve, and other tissues.
In the human body there are five important types of cells. Epithelial cells make up the skin and the glands, and line the blood vessels. Muscle cells make up the three kinds of muscles. Nerve cells make up the brain, spinal cord, and nerves. Blood cells are found in the blood and lymph. Connective tissue cells make up the framework tissue of the body.

The circulatory system, in higher forms of living, carries food and oxygen to every cell and removes waste products, like carbon dioxide. The individual cells combine the food and oxygen slowly, thus obtaining the heat and energy necessary for their life and work. It is because of this energy that muscles can contract, nerves can conduct messages, and the brain can think.

A cell is the very smallest unit of living matter all living things including plants and animal cells cells are made up of atoms which are the smallest unit of matter there are many types of cells the ones we most likley know are animal and plant cells the differance is that a plant cell has a cell wall and chloroplast.

Cells all have differant shapes and sizes the biggest cell is the yolk of a ostrich's egg.

All cells have some parts the same one part found in all cells is the cell membrane this cell membrane surronds the cell and holds it together anougher thing most cells have is a Nucleus this is a dark structure located in the middle of the cell.

Like all living things cells die in a minite about three thousand cells will die in that same minite about anougher three thousand cells would have divided to replace the ones that had just died

the lenght of time a cell can live varys for example a white blood cell lives up to eighteen days where as a red blood cell lives up toa hundred twenty four days the nerve cell lives up to 100 years !

A cell is the smallest matter ever found. Matter is what makes materiel and objects.
