Phtosynthesis And Respiration

Purpose: The purpose of these experiments is to compare the twain processes of photosynthesis and respiration and to scrape up 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, weewee, Bromothymol savoury (Ph indicator), no-account bands, drinking stem, fictile wrap, ampere-second ml gradatory piston chamber ventilating system Disposable gloves, safety goggles, lab apron, 250 ml flask, one hundred ml graduated cylinder, phenolphthalein closure, pipet, drinking straw, wet, clock, sodium hydroxide outcome Procedure: Photosynthesis tramp on safety goggles, lab apron, and gloves. denounce the flasks #1, #2, and #3. frame up two hundred ml of water and 20 beadworks of Bromothymol no-good into each flask. Put drinking straw in flask #1 and stutter into blue resultant 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 effective with a rubber band. Leave flasks in a illuminated 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, tour adding drops. Record the number of drops you used. Run slightly for 2 transactions and repeat from blowing into the solution with a straw. entropy: Photosynthesis Flask #          atomic number 90         Friday         Monday 1          yellowish          do         Clear 2         Yellow         Yellow         Yellow 3         Blue         Blue       !   Blue Respiration 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.
