intracellular reactions occur in an aqueous environment Water H 2 O is a chemical compound consisting of two hydrogen atoms and one oxygen . The Most . I. mportant Nutrient. By: Casha and Chase. Water is the most overlooked of all the 6 Nutrients. Water is very essential to the body. It has to be replaced everyday. You can only survive a few days without it. Water intoxication, or water poisoning, is a potentially deadly condition.. How can drinking too much water kill you?. Remember – materials move across the cell membrane because of concentration differences.. Imagine an inverted test tube with a column of water in it. The volume above the water is empty (no air). The piston underneath is free to move up and down with no friction. If the water is not moving, what can you say about its weight?. Leaving Certificate Biology. Higher Level. Selective Permeability. Cell membranes are selectively permeable meaning they can control what enters and leaves the cell. Selective permeability is controlled by proteins embedded in the cell membrane. living with the lab. © 2011 David Hall. the world’s oceans contain an average of about 3.5% salt by weight .

Water Absorption: Organ, Mechanism: . Absorption of water and nutrient is carried by the younger portions of a root, near its tip. The very tip is covered with a sheathing root cap which protects the delicate underlying tissues as the root pushes its way through the soil..
