Question

What is mean by osmosis and mitosis
?

Answer 1

Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
Mitosis is the process by which a cell duplicates into two daughter cells. In mitosis, chromosomes in the cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus. It is a form of nuclear division

Answer 2

Large quantities of water molecules constantly move across cell membranes by simple diffusion, but, in general, net movement of water into or out of cells is negligible IS CALLED OSMOSIS. For example, it has been estimated that an amount of water equivalent to roughly 250 times the volume of the cell diffuses across the red blood cell membrane every second; the cell doesn't lose or gain water because equal amounts go in and out.

Mitosis is a process of nuclear division by which replicated copies of a cell's DNA. are organized into chromosomes. Tin mitosis, the dissolution and reformation of nuclear membranes, the. formation of the mitotic spindle, and the division of the cytoplasm.
