Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

wavelengths of light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best results of photosynthesis as compared

Question/Purpose: The Question or Purpose of our lab is to answer the question “How is the germination of a seed affected by sunlight?” Experimental Hypothesis: We believe these results will occur. 1. The seeds that are water deprived (1 mL of H2O a day) will not grow very well due to a lack of water which is important in photosynthesis and also lacks nutrients. The seeds may also die off due to a lack of water. 2. The seeds that are have a proper amount of water (10 mL of

Investigation 5: Photosynthesis Problem: If the leaf disks are treated in a way you know increases the net rate of photosynthesis‚ should they start to float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source‚ then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore‚ shining a red light source onto the leaf disks would cause them

Abstract For this lab the rate of photosynthesis was analyzed upon plant leaves. A sample of a light exposed and a not-light exposed leave were used to clearly identify the role of sunlight in the process of producing and storing energy. Aim We are trying to find proof‚ to demonstrate the necessity of light and chlorophyll in the process of photosynthesis. Background Photosynthesis occurs in organisms which contain chlorophyll. It’s a process that involves the chloroplasts to synthesize glucose

Biology (D) Ms. Wainman The relationship between Photosynthesis and cellular respiration Introduction: Photosynthesis is the process which used by plants to capture light energy and use it to do chemical reactions that change carbon dioxide and water into oxygen and energy (ATP)‚ carbohydrates just like sugar. Cellular respiration is the process that releases energy by breaking down glucose and other food with oxygen. Plants cells do photosynthesis and cellular respiration both ‚but animal cells

in water on the rate of photosynthesis. Aim: The aim is to investigate how increasing carbonate in water can affect the rate of photosynthesis. Introduction: The rate of photosynthesis can be increased or decreased in many different ways. For example‚ by adding substances like alkaline or salt to the water‚ you can increase or decrease the acidity or basics‚ if the water has too much acidity‚ it can often delay the rate of photosynthesis‚ often stopping the rate of photosynthesis in the plant‚ which

Discussion: We have made four set-ups in two different specimens. Onion and Boat of Moses skin with water‚ 2%‚ 5% and 10% salt (NaCl) Solution. Based on our experiment‚ the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplast. In table 1‚ we have observed under the microscope that the onionskin mounted with water has no results of plasmolyzed cell (0%). This time‚ we have repeated the procedure with 2% salt

GLENDA MARIE GARCIA POLARIZED LIGHT LAB REPORT EXPERIMENT # 5 June 27‚ 2014 PHYS 1417 ABSTRACT Ordinary light such as that from a light bulb is a form of wave motion that consists of electrical and magnetic fields that vibrate at right angles to the direction of travel of a light beam. Light waves that vibrate in a single plane are called polarized light waves. Such waves can be produced by passing light through polarizing filters. The experiment conducted was composed of crossed
