Are you aware that all organisms, even the largest, start their life from asingle cell? You may wonder how a single cell then goes on to form such large organisms. Growth and reproduction are characteristics of cells, indeed of all living organisms.

All cells reproduce by dividing into two, with each parental cell giving rise to two daughter cells each time they divide.

These newly formed daughter cells can themselves grow and divide,giving rise to a new cell population that is formed by the growth anddivision of a single parental cell and its progeny.

In other words, suchcycles of growth and division allow a single cell to form a structureconsisting of millions of cells
