Osmosis is specifically the movement of water through membranes.We observed different solutes (NaCl, Ovalbumin, Glucose, Sucrose, and Water) in the dialysis tubing.Hypotonic is when the solution has a lower solute concentration compared to the water potential.In an isotonic solution, there is no net movement and there is an equal concentration of solutes and water.Water goes through the cell membranes by diffusion.

 The word ‘osmosis’ is particular to the diffusion of water molecules into the cell.When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration (e.g.Reverse osmosis desalinators use pressures around 50 atm to produce fresh water from ocean salt water.Part of the chamber opens to a differentially permeable membrane that lets water molecules through, but not the solute particles.The water to be purified is placed in a chamber and put under an amount of pressure greater than the osmotic pressure exerted by the water and the solutes dissolved in it.

Inside the gills of aquatic animals, the circulatory system removes oxygen, and delivers waste carbon dioxide.Air enters through the nasal passages, or the mouth, passes through the trachea, then branches off at the two bronchi, and goes through many branching passages called bronchioles, which end in alveoli.Four problems faced by animals on land are breathing (respiration), water conservation in excretions, successful reproduction, and the producing an egg which can survive outside of the water.Alveoli are sack-like structures where the circulatory system meets the respiratory system.Terrestrial vertebrates have developed lungs to solve this problem.

Blood is flowing in the opposite direction so it can absorb most of the oxygen, that is in the water.If the blood were to move with the water an equilibrium point may be reached and only half the oxygen would be absorbed.(air as more oxygen than water does) Lungs need 1 to 2 percent of the energy in an organism, while gills need 25 percent.The countercurrent flow allows the fish to absorb 80 to 90 percent of oxygen in the water.This may sound like gills extract a high amount of oxygen, but when you compare water and air with the same volume, you will find that water has 3 percent of the oxygen that is in air.

The low water potential reduces the evaporation o water from the cell surfaces as the water potential gradient between the cells and the leaf air spaces is reduced.Water moves from an area of high water potential to an area of lower water potential, and this is what causes the water vapour in the plant to be lost to the outside atmosphere, due to the difference in the water potential gradient, and we call this “moving along the water potential gradient”.If the water potential outside the plant was higher than the water potential inside the plant, then the plant would absorb water vapour rather than lose it, but because of the extreme weather conditions, and the difference in water potential the plant loses rather than gains water.This is...
