When you jump in the bath, water does not run around all your cells and directly into your body. Instead water intake and release is regulated by special proteins called aquaporins. Why can't water run around your cells but instead has this regulation? Select one: a. Water is nonpolar, like our bodies and so cannot mix easily. b. Because we live in a hypertonic environment anyway. c. Desomosomes and gap junctions provide orientation for water movement. d. Our epithelial (skin) cells have tight junctions which form a 'water-tight' seal between cells preventing substances from going around the cell.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
