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

plants would not be able to carry out photosynthesis (McKenney‚ Peffley‚ and Wilmington 49). Photosynthesis is responsible for providing the plant with nutrients it needs to thrive and grow. Without the proper nutrients‚ it is difficult for a plant to continue to live. Therefore‚ photosynthesis is necessary for a plant’s vitality. The goal of this experiment is to observe and identify the impact that light has on a plant. Hypothesis: If light affects photosynthesis in plants‚ then the plants growing

Artificial intelligence can be viewed as a pro or a con depending on whom you talk to. First off‚ the definition of artificial intelligence is the science and engineering of making intelligent machines‚ especially intelligent computer programs. The most controversial part in this topic is the understanding of how much intelligence is going to be instilled in computer and machines. This makes many people nervous about the possibility of these machines and computers malfunctioning to the point of disaster

purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the first 7

Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However‚ the reactants and the products are exact opposites in photosynthesis and in cellular respiration. In photosynthesis‚ cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun‚ and then the cells release oxygen (O2) and store glucose (C6H12O6). The formula of photosynthesis is: Light energy 6CO2+6H2O → C6H12O6+6O2

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

Lab Report #1 Photosynthesis Lab Report: The Effects of Varying Concentrations of CO2 on the rate of Photosynthesis in Spinach Leaves Introduction Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. The purpose of this experiment is to see how different concentrations of carbon

one were to take a look around the room they are currently in‚ chances are there would be some form of artificial intelligence present. From cell phones to computers – artificial intelligence is everywhere and even a way of life. The next generation of people may never know what life is without some form of intelligence embedded into their everyday schedule and routines. Perhaps the coffee pot that brews their caffeinated beverage every morning is programmed in such a way that they don’t even have

The Benefit of Artificial Intelligence in the World Diana Carter INF 103 God Jesus January 10‚ 2010 Abstract Artificial intelligence technology has yet to show the world of its capabilities but in due time it will be evident. Artificial intelligence (AI) is referred to as a computer and robot that is able to model human-like tasks without being told to do so. AI is used around the world everyday by humans for their own beneficial use. Many may not know it‚ but AI is the core to many of our
