Misael Acosta Photosynthesis Lab Report Ms. Rocha AP Biology 4th Period II. Intro/Background 1. In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CO2‚ and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of O2 or the consumption of CO2. All the oxygen within the leaf disks will be removed before being placed

AP Biology Photosynthesis Lab Bethany Boyer Due 11/12/14 Lab Write-Up Questions First Experiment 1) The independent variable in this experiment was the presence of CO2 (carbon dioxide). The dependent variable was the speed at which the leaf disks started to float. 2) In the leaf tissue‚ the bicarbonate and light are combining to carry out photosynthesis. This will cause oxygen to collect in the leaf tissue‚ causing it to rise. 3) If we were to boil the leaf disks‚ the reaction would most likely

How does photosynthesis model the Law of Conservation of Matter and The Law of Conservation of Energy? Photosynthesis models the Law of Conservation of Matter and the Law of Conservation of Energy‚ and there is evidence from some articles that were read to prove this statement. First‚ the Law of Conservation of Matter is modeled in photosynthesis‚ because in the Photosynthesis for Kids article it stated‚”Photosynthesis occurs when Chlorophyll‚ a green pigment that collects lights‚ consumes radiant
