Purpose: The purpose of these experiments is to compare the two processes of photosynthesis and respiration and to find take place to the fore what they do. Equipment: Photosynthesis spendable gloves, testing ground apron, gum elastic goggles, two 5 cm sprigs of elodea, three 250 ml flasks, water, Bromothymol savoury (Ph indicator), rubber bands, potable straw, bendable wrap, ampere-second ml gradatory cylinder ventilating corpse Disposable gloves, sentry go goggles, lab apron, 250 ml flask, century ml graduated cylinder, phenolphthalein solution, pipet, drinking straw, water, clock, atomic number 11 hydroxide solution bit: Photosynthesis tramp on safety goggles, lab apron, and gloves. Label the flasks #1, #2, and #3. fix up two light speed ml of water and 20 drops of Bromothymol hot into each flask. drop drinking straw in flask #1 and stumble into blue solution until it turns yellow. In flask #2 do the same as in flask #1. Put unmatched elodea sprig into flask #1 and the other peerless into flask #3. Do postcode to flask #2. Cover flasks with fictile wrap and secure with a rubber band. Leave flasks in a well-lighted field of operation and leave them overnight. disposition observations. breathing Put on safety goggles, lab apron, and gloves. Put 50 ml of water and intravenous feeding drops of phenolphthalein to the flask. Using the drinking straw, subdued blow into the solution for 1 minute. Add the sodium hydroxide one drop at a time, and gently poke out the flask. When the liquid turns pink, stop adding drops. Record the number of drops you used. Run passably for 2 minutes and repeat from blowing into the solution with a straw.
