Question

why do unicellular organisms go away from each other but why can't they form tissues? eg;Amoeba divides and separates why can't they form tissues

Answer 1

Mitosis is a form of cell division that results in two daughter cells that are genetically identical to each other and to the original cell. Mitosis plays an important part in the life cycle of most living things, though to varying extents. In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair. The importance of mitosis for the individual is influenced by whether it is single-celled or multicellular organism.
