Some leaves are very short, as short as they cannot be seen through naked eyes where as there are big broad leaves that can form many umbrellas for small children.
Processes of Life
All those processes that maintain the body of an organism collectively are called as life processes. These processes principally include Nutrition, Respiration, Internal Transport, and Excretion. Some other processes of life like control and coordination, Reproduction, Heredity and Evolution etc. are essentially found in living beings but they are not directly related to processes of life. Hence, these may or may not be regarded as life processes
