We will attempt this investigate by use an exponent called bromthymol blue. This indicator will rhythm yellow if carbonic acid gas is present during cellular respiration and during photosynthesis the indicator will sprain from yellow to blue if the CO2 has been imprisoned by the plant. II. declare oneself To demonstrate that CO2 is used during photosynthesis. To demonstrate that CO2 is produced during cellular respiration. III. Hypothesis 1. If we put elodea, bromthymol blue, tonic wet, and systematic water system in a phial in the sunlight then we shack demonstrate that carbon dioxide is used during photosynthesis because the indicator will identification number blue. 2. If we put elodea, bromthymol blue, and regular water in a ampule in the dark then we can dem onstrate that carbon dioxide is produced during cellular respiration. IV. Materials 1. Bromthymol blue 2. Capped vials (Gerber baby food jars) 3. pondweed (aquarium plant) 4. Light and dark areas. V. Procedures 1.Divide into a group of 4 2. add to draw offher in one person to get two vials 3.Send virtually other person to get 2 healthy green plants of elodea 4. throw 2 elodea in severally jar 5.Fill the two jars with water up to ¾ of the jar 6.Get a dropper and pull back bromthymol blue into the dropper 7.Fill some(prenominal) jars each with 70 drops of bromthymol bblue 8.Get a different dropper and string up sparkling water water with it 9.Add in 20 drops of seltzer water in only one jar 10.Securely go game up both jars with their cap 11.Put the jar that has the seltzer water in it in the sunlight 12.Put the jar that just has the elodea, bromthymol blue, and regular water inside a dark areaIf you want to get a full essay, order it on ou r website: BestEssayCheap.com
