Detailed explanation-1: -These single cells fuse and give rise to multicellular organisms. An adult human body has approximately 100000 million cells. Note: As a person ages, the number of healthy cells will decrease. In the new-born infant, the number of cells is approximately 26, 000, 000, 000.
Detailed explanation-2: -A cell is the smallest unit that is typically considered alive and is a fundamental unit of life.
