AP Biology Lab 4 - Plant Pigments & Photosynthesis
During the process of photosynthesis, carbon dioxide is absorbed by leaves while oxygen is released.
However, when the leaf is exposed to light oxygen will be present in the leaf again.
different colored leaves
source of light
put one 1cm of alcohol solvent in the 50ml cylinder
use filter paper and draw a line 1.5 cm from the bottom of the paper
place spinach leaf over the pencil line on paper to extract pigment
place chromatography paper in alcohol solvent
mark location of solvent when it is 1cm from the top of the paper
measure distance each pigment migrated
record distance and calculate reference front
Sunlight is not constant throughout the lab ( clouds changing the amount of sunlight on the leaf disks)
Place 500 mL of water with 10 g of sodium bicarbonate
punch 40 holes from each dark green, green, red leaves
place leaf disks in syringe (to get rid of oxygen)
distribute 10 leaf disks evenly in the solution of the 4 (40 mL-sized) beakers
place beakers in sun
use stop watch to time how long the 4 first leaf disks (of one color) rise
repeat process 4 times for each colored leaf
