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

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

experiment consisted of three smaller experiments as a result of the different properties chlorophylls possess and the need to test them individually to receive the most accurate results. Preparation for the lab began with selecting a medium to large spinach leaf and deveining it. Once the spinach was prepared‚ it was ground in 5 mL of 100% acetone‚ creating a green acetone extract. The extract was filtered through a funnel with a kimwipe and into a test tube. The volume of the filtered extract was

The results of the food coloring exercise are seen in Figure 1 of the group report. The red food coloring displayed the highest percent transmittance in the long wavelengths closest to red light‚ which was expected. With the same logic‚ it was expected that the blue food coloring would have the highest percent transmittance in

Introduction The lung is a spongy organ made up of of irregularly shaped air spaces called Alveoli. The alveoli are lined by a single layer of flat cells and supported by a mesh of fine elastic fibers. The alveoli are surrounded by a rich network of pulmonary capillaries (Couch and Berger‚ 2004). Our lungs are a network of connected tubes that bring oxygen from the air into our blood‚ nourishing the trillions of cells that make up our bodies. The lungs also clean the blood of carbon dioxide waste

Through this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the

Title of Experiment Extraction of Spinach Date that the Experiment was Performed This experiment was performed on Wednesday‚ September 17th‚ 2014 at 2:45 pm in the St Ignatius Science Center Laboratory 323. Partners Names Taylor Jackson and Matt D’Angelo. Taylor‚ Matt‚ and I shared the same data. Purpose/Goals/Objectives The purpose of this experiment was for each student to use column chromatography to separate plant pigments from spinach leaves. Some goals and objectives were to

Practical 5: determination of activation energy of an enzymed catalyzed reaction Introduction: enzymes are complex chemicals that control reactions in living cells. They are biochemical catalysts‚ speeding up reactions that would occur too slowly to be of any usefulness to an organism. Although in organisms‚ it is not necessary for the reactions to be at maximum rate at all times. Enzymes interact with other molecules to produce a stable system in which the products are made when they are

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
