Phtosynthesis And Respiration

Purpose: The purpose of these experiments is to compare the 2 processes of photosynthesis and respiration and to remark come to the fore what they do. Equipment: Photosynthesis spendable gloves, lab apron, safety goggles, two 5 cm sprigs of elodea, three 250 ml flasks, irrigate, Bromothymol savoury (Ph indicator), base hit bands, drinking cover, fictile wrap, ampere-second ml gradatory cylinder ventilating system Disposable gloves, safety goggles, lab apron, 250 ml flask, century ml graduated cylinder, phenolphthalein radical, pipet, drinking straw, body of water, clock, sodium hydroxide ancestor Procedure: Photosynthesis tramp on safety goggles, lab apron, and gloves. estimate the flasks #1, #2, and #3. frame up two hundred ml of water and 20 fails of Bromothymol mordant into each flask. Put drinking straw in flask #1 and stutter into blue resultant role until it turns yellow. In flask #2 do the same as in flask #1. Put matchless elodea sprig into fla sk #1 and the other peerless into flask #3. Do nothing to flask #2. Cover flasks with fictile wrap and dear with a rubber band. Leave flasks in a well-lighted area and leave them overnight. Record observations. Respiration Put on safety goggles, lab apron, and gloves. Put 50 ml of water and four drops of phenolphthalein to the flask. Using the drinking straw, piano blow into the solution for 1 minute. Add the sodium hydroxide one drop at a time, and gently offer the flask. When the liquid turns pink, soften adding drops. Record the number of drops you used. Run slightly for 2 proceeding and repeat from blowing into the solution with a straw.
