This happens during metaphase. I remember this phase because it is the move phase
of mitosis. The m from move matches the m from metaphase.
In mitosis, it happens during metaphase.
In meiosis, it happens twice and occurs in metaphase 1 and metaphase 2
No. Osmosis is the movement of a solvent through a membrane (semi-permeable) from a less concentrated solution to a more concentrated solution to the point where the two sides reach equilibrium. Isotonic solutions are solutions where the two sides of the membrane are already at equilibrium - so there is no movement of the solvent (like water) - so this is different from osmosis.
