Abstract: The rate of photosynthesis and cellular respiration can change in varying conditions. How does the rate change with varying degrees of temperature and light exposure? To test this algae beads were exposed to a CO2 indicator‚ which changes colors based on the level CO2 level present. The algae beads were exposed to two different variables‚ light and temperature and tested for color change‚ Ph‚ level‚ and CO2 absorbance level. The beads were exposed to a light and a dark condition‚ and another

Introduction Photosynthesis is a well perceived performance in which plants and other defined organisms use the energy of photons to convert carbon dioxide and water into a simple monosaccharide sugar known as glucose. Photosynthesis provides the fundamental energy source for essentially all living organisms. The most substantial and valuable byproduct of photosynthesis is oxygen‚ one of the most abundant elements living organisms depend on. Photosynthesis occurs in many organisms

rate of photosynthesis increased from a cold temperature to room temperature; however‚ the rate of photosynthesis decreased in the body temperature. This means that the hypothesis was rejected. The rate of photosynthesis did increase‚ but only to a certain point. Based on these results‚ it can be concluded that photosynthesis performs better at room temperature that at cold temperature because thee low temperature slows down the reactions taking place in the chloroplasts. Photosynthesis performs

This means that the light intensity actually has an impact on the plant’s photosynthesis levels. The reason that there are more bubbles in the experiments with more light is because of the oxygen release rate. With more light intensity‚ the rate of photosynthesis happens faster. Since the process of photosynthesis release oxygen‚ the more oxygen will be released creating the bubbles underwater. To clarify‚ photosynthesis is the process of which a plant’s chloroplasts‚ with the aid of the sun (or

Photosynthesis is the process in which autotrophs use light energy to convert carbon dioxide and water into glucose. This conversion into chemical energy is associated with the action of the green pigment chlorophyll. Chlorophyll molecules located in the thylakoid membrane of the chloroplasts are arranged into complexes known as photosystems. Each photosystem contains the reaction center complex and is surrounded by light harvesting complexes. The light harvesting complexes are composed of pigment

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

them to the appropriate position. Perform the same process by changing the degree of the objective lens and focus to be able to see the grid clearly. Using Egeria densa‚ cut a leaf using a scissor and place it onto the slide glass using a forcep and using the droppers drop some water and place coverslip on top of the leaf by sliding the coverslip when placing on top to prevent air which produces bubbles. Place the slide glass on the stage‚ by moving the stage clip and move the coarse adjustment

affect Photosynthesis? 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. It produces sugar and other organic compounds such as lipids and proteins. The sugars are then used to provide energy for the organism. Light reaction is the series of biochemical reactions in photosynthesis that
