A view of life.

Life! its every where on earth,you can find living organisms from the poles to the equator, from the bottom of the sea to several miles in the air, from freezing waters to dry valleys to undersea thermal vents to ground water thousands of feet below the earths surface. living organisms have diversified and adopted to almost every environmental condition. The diversity of life is truly amazing.
planet earth is home to trillions of organisms (living things), including animals and plants. they are found on land, in lakes, rivers and oceans, as well as in the air. Cells are the basic unit of life. A cell is the smallest unit of a living thing, whether made of one cell(like bacteria) or many cells (like human), is called an organism. Thus cells are the basic building blocks of all organism. Several cells of one kind that interconnect with each other and perform shared function form tissues, several tissues combine to form an organ( heart, brain, stomach), and several organs make up an organ system( such as digestive system, circulatory system, nervous system). Several systems that work together form an organism(like a human being). Your body has many kinds of cells, each specialized for a specific purpose, just as home is made of variety of building materials, the human body is formed from many cell types, each cell type plays a vital role during the growth, development and day to day maintenance of the body.
