The purpose of this lab was to; observe the breakdown of hydrogen peroxide toxin by potato’s enzyme catalase‚ determine factors that influence how quickly the reaction takes place‚ and determine factors that influence how well enzymes function. The first test‚ we were supposed to see what would happen when we add sand in hydrogen peroxide. We filled a test tube with 5mL hydrogen peroxide and we added

involves osmosis which is hypotonic‚ hypertonic and isotonic. In a hypotonic solution‚ the water will move into the cell due to the outside of the cell having a lower solute concentration than the inside of the cell. When an animal cell is placed in a hypotonic surrounding (lower solute concentration)‚ the water molecules will move into the cell causing the cell to burst and haemolysed. When plant cell is placed in a hypotonic solution‚ water molecules diffuse into the cell and the plant cells remain turgid
