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 mon complicated living things work together. They are organized in groups, each of which has some special work to do for the plant or animal.

What Does A	Cell	Do

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 flake up the three kinds of Nerve cells that 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.

What Are The 7 Functions Of A Cell?

1: Movement (muscle cells) 2: Conductivity (nerve cells) 3: Metabolic absorption (kidney and intestinal cells) 4: Secretion (mucous gland cells) 5: Excretion (all cells) 6: Respiration (all cells) 7: Reproduction (all cells).
