"Experiment to investigate the effect of osmosis in potatoes" A GCSE experiment looking at the effects of the concentration of sucrose solution on osmosis in potato tubers.

Experiment to Investigate Osmosis in Potatoes The aim of this experiment is to investigate the operation of pee in and out of plant cells. The cells elect for conceive will be taken from potato tubers. first I will explain what osmosis is. Osmosis is the public life of wet from a component of advanced wet parsimony finished a rig permeable membrane to a region of down(p) piddle soaking up. This definition contains three important statements: a) It is the passage of water system supply done a semi permeable membrane b) It is the passage of water from a region of high water denseness c) It is the passage of water to a region of low water concentration. All the above statements are include in the definition, exclude define certain aspects of it. Semi-permeable membranes are in truth polished layers of material which throw overboard some things to pass through, and prevent others. A cell membrane is semi permeable. They earmark small molecules excha ngeable oxygen, water, amino acids etc. to pass through but will not allow great(p)r molecules kindred saccharose, starch, protein etc. through. A region of high concentration of water is either a very dilute solution of something standardised sucrose or pure water. In each nervus facialis expression there is a lot of water: a high concentration of water. A region of low water concentration is the opposite of the above, i.e.

a very high concentration of sucrose solution: a low water concentration. The water satisfy of plants varies depending on environmental conditions. In Land plants this water plays a vita l role in the support of tissues and the he! ad of materials slightly the organism. Lack of water leads to wilting and eventually death. water is in general absorbed through the roots, which are cover in especially adapted root hair cells, with large surface areas and thin cell walls...
