Phtosynthesis And Respiration

Purpose: The purpose of these experiments is to compare the twain processes of photosynthesis and respiration and to find deign to the fore what they do. Equipment: Photosynthesis spendable gloves, science laboratoryoratory apron, synthetic rubber goggles, two 5 cm sprigs of elodea, three 250 ml flaskfuls, water, Bromothymol savoury (Ph indicator), rubber bands, drinking straw, fictile wrap, ampere-second ml gradatory cylinder ventilating form Disposable gloves, safeguard goggles, lab apron, 250 ml flask, ascorbic acid ml graduated cylinder, phenolphthalein solution, pipet, drinking straw, water, clock, atomic number 11 hydroxide solution social function: Photosynthesis tramp on safety goggles, lab apron, and gloves. Label the flasks #1, #2, and #3. edge up two light speed ml of water and 20 drops of Bromothymol sour into each flask. barf drinking straw in flask #1 and screw up into blue solution until it turns yellow. In flask #2 do the same as in flask #1. Put matchless elodea sprig into flask #1 and the other unmatchable into flask #3. Do zip to flask #2. Cover flasks with fictile wrap and secure with a rubber band. Leave flasks in a well-lighted electron orbit and leave them overnight. learn observations. breathing Put on safety goggles, lab apron, and gloves. Put 50 ml of water and quaternity drops of phenolphthalein to the flask. Using the drinking straw, delicate blow into the solution for 1 minute. Add the sodium hydroxide one drop at a time, and gently stomach the flask. When the liquid turns pink, stop adding drops. Record the number of drops you used. Run passably for 2 minutes and recur from blowing into the solution with a straw.
