Every living organism has a life cycle involving its birth, growth and death. |
| |
|
The duration of life between the birth and death of an organism, represents its life span. This ranges from as little as a few minutes to as long as thousands of years, in different species of plants and animals. |

|
The phenomenon of death has some specific biological significance. |
| |
|
It is a regulatory process in nature, which maintains a balance in the population of a species. |
| |
|
The death of an organism allows decomposition activity of bacteria and fungi, which brings about recycling of materials. |
| |
|
Dead cells in the body have a significant role in providing protection (as in the outer most layer of our skin). |
| |
|
Dead cells in the plant body form tissues like sclerenchyma, which serve mechanical functions. |
