Explanation:
The force required to prevent the movement of water across a selectively permeable membrane is osmotic pressure. The plasma membrane forms a vesicle around the substances to be transported, and the vesicle around the vesicle is taken into cells.
Osmotic pressure depends on both the pressure gradient and concentration gradient. This is only affected by the temperature and concentration of solute, each affect the movement of water across a membrane.
Higher the concentration is higher temperature increases osmotic pressure, which produced or associate with osmosis and dependent on molar concentration and absolute temperature. Hydro-static pressure forces fluid out of the capillary , osmotic pressure draws fluid back in.
