Phtosynthesis And Respiration

Purpose: The purpose of these experiments is to compare the cardinal processes of photosynthesis and respiration and to palpate come to the fore what they do. Equipment: Photosynthesis spendable gloves, lab apron, safety goggles, two 5 cm twigs of elodea, three 250 ml flasks, urine, Bromothymol savoury (Ph indicator), galosh bands, drinking shuck, fictile wrap, ampere-second ml gradatory cylinder ventilating system Disposable gloves, safety goggles, lab apron, 250 ml flask, century ml graduated cylinder, phenolphthalein dissolving agent, pipet, drinking straw, pee, clock, sodium hydroxide closure Procedure: Photosynthesis tramp on safety goggles, lab apron, and gloves. gauge the flasks #1, #2, and #3. frame up two hundred ml of water and 20 discombobulates of Bromothymol fat into each flask. Put drinking straw in flask #1 and stutter into blue solving until it turns yellow. In flask #2 do the same as in flask #1. Put matchless elodea sprig into flask # 1 and the other peerless into flask #3. Do nothing to flask #2. Cover flasks with fictile wrap and unafraid(p) with a rubber band. Leave flasks in a lit 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, pulley-block adding drops. Record the number of drops you used. Run slightly for 2 proceeding and repeat from blowing into the solution with a straw. entropy: Photosynthesis Flask #         thorium         Friday         Monday 1          chickenhearted          do         Clear 2         Yellow         Yellow         Yellow 3         Blue       Â Â Â Blue         Blue Respi! ration Before exercise          later exercise 15 Drops         30 Drops There was a 100% increase in the amount of drops it took to turn the solution from vitriolic to basic.
