Characteristic of Life

"One or more cells compose all living things. Each life form begins from one cell.Organization patterns are found in all living things. Organisms use energy. The chemical energy they use is called metabolism. Plants use energy from the sun to make their own food. Humans and animals ingest for this purpose.In order to remain alive, there are internal conditions that need to be maintained.

These include temperature, water content, heartbeat and other such things. All conditions are not necessary to maintain the body, but most are.Organisms grow and change. Cells divide to form new ones. When organisms grow and change, it is called development.When organisms reproduce the new organism will have some characteristc from the mother and some from the father. It may look like either of them, or it may not. This is called sexual reproduction. In summary, all living things have cells which are building blocks of life. Living things eat, drink, breathe, excrete and reproduce."
