allows water to be used for the transportation of such substances (notably in the bloodstream of animals and the xylem and phloem vessels found in plants). Water can be used in this way to transport many substances: nutrients‚ excretory products (eg urea‚ ammonia)‚ hormones and digestive juices can all be transported by using water as a solvent. Molecules such as starch and glycogen which are hydrophobic are not soluble and therefore are ideal for storage. In the digestive system many polymers and

stimulation of the maggots crawling over the wound33 although this is now considered unlikely. Allantoin‚ (2‚5-Dioxo-4-imidazolidinyl) urea‚ a product of purine metabolism found in maggot secretions but first isolated from Comfry root and still used today in some cosmetics and pharmaceuticals‚ was claimed to be responsible for this effect34. Ammonium bicarbonate21 and urea‚ too‚ were found to be active constituents. Subsequently‚ allantoin and urea35 ammonium bicarbonate21 and mixtures of calcium carbonate

1 Experiment Membrane Transport Objectives ► Referring to energy‚ what two ways can substances enter a cell? What is active transport? What is passive transport? How is osmosis related to diffusion? How can we demonstrate active transport? How can we demonstrate Brownian movement? How can we demonstrate diffusion (2 ways)? How can we demonstrate osmosis (3 ways)? In terms of relationships between substances‚ how can we define “hypertonic”‚ “isotonic”‚ and “hypotonic”? What is the relationship
