Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing‚ photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen‚ on which most organisms depend. Photosynthesis occurs in green plants‚ seaweeds‚ algae‚ and certain bacteria. These organisms are veritable sugar factories‚ producing millions of

Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air‚ but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air. Here is a molecular model of a glucose molecule. You do not need to memorise the diagram for you GCSE exam‚ but it should help you to understand that a molecule of glucose contains six atoms of Carbon (shown in blue)‚ twelve

The Rate Of Photosynthesis: Lab report 1) Construct a graph of your data 2) Using the graph‚ estimate the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

Rocky Shore Ecosystems- Point Cartwright Nicolas Cuny 11B Mr. Nisbett Due Date: 03/09/2010 Introduction: On the 23rd of August‚ the three biology classes or grade 11 at Redlands College visited the rocky shore ecosystems at Point Cartwright in Queensland. Two different types of rocky shore ecosystem were examined‚ the rock pool area‚ and the boulder area. We first examined areas within the rock pool area. The rock pool area has several specific features

bean would affect its rate of respiration. Splitting a bean does not impact its rate of respiration. This is shown in the data‚ while the average rate of respiration for Whole beans is 1.35 and the rate of respiration for 1.16‚ the standard error of the mean is .15. Because the standard error of the mean is so high‚ they overlap in both of the data sets‚ which shows that the data is very similar. This is better shown in the graph‚ which has error bars shows just how close the two data sets are.

I can model Photosynthesis with The Law of Conservation Of matter and The Law of Conservation of energy. I know this because of the articles i’ve read the articles are Discovering the secrets of Photosynthesis‚ Joseph Priestley‚ Discoverer of Oxygen and Photosynthesis: Yucky chemistry Details. Photosynthesis is a good example of the Law of conservation of Energy because in the process of Photosynthesis the radiant energy is absorbed by the plant. The radiant energy is then turned into chemical

PHOTOSYNTHESIS LAB Alyssa Wright VARIABLE: LIGHT INTENSITY AIM: to investigate the effect of light intensity (lux) on the amount of oxygen produced (number of bubbles) HYPOTHESIS: I predict that the rate of oxygen produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen
