Life starts from a single cell called a zygote. It divides repeatedly through mitosis to form many cells. These cells differentiate into tissues organs and organ systems, eventually developing into a complete multicellular organism with specialised functions.
Life begins when a single cell divides itself several times to give rise to a large number of cells. Explain.

Life begins with a single cell that continuously divides to produce many new cells. These cells gradually become specialised through differentiation and form tissues organs and organ systems. Different tissues perform specific functions like protection, movement and coordination. This organised development transforms one cell into a complete multicellular organism capable of carrying out all important life processes.
