The Graph that goes along with the table:
| Orange line represents the Dry Peas and Beads at 11° |
| Blue line represents the Germinating Peas at 11° |
| Red line represents the Dry Peas and Beads at 20° |
| Green line represents the Germinating Peas at 20° |
The reason for the absence of the Beads alone on the graph is simply
because the Beads do not respirate. Their only purpose in this lab
was to serve as a control to measure the changes in atmosphereical
pressure. From the results protrayed in our lab, the conclusion can be
made that Germinating Peas in warm water increase consistantly with
time, Germinating Peas in cold water consume the most water in the first
5 to 10 minutes. After that point, the rate of respiration begins to
decrease. The rate of respiration of Dry Peas in cold water increases
as time increases. Dry Peas in warm water do not respirate (this may
be an inaccurate result because dry peas are still plants).
