Process of photosynthesis

All organisms on earth depend on photosynthesis, in which light energy is used to make sugar and other food molecules from carbon dioxide and water. For example, plants and other photo-synthesizers need only energy from sunlight, carbon dioxide from air, and water from the soil to make the sugar glucose. Photosynthesis is the most important chemical process on earth because it provides food for virtually all organisms, not only for photo-synthesizers but for the organisms that eat them. Plants can

Abstract: During photosynthesis plants take light energy and turn it into chemical energy. The purpose of the study was to test the effect of various lighting conditions on the rate of photosynthesis. In this experiment the rate of photosynthesis is measured by timing how long it takes photosynthesis to occur in ten leaf disks that are in a solution of carbon dioxide. The prediction for this experiment was that if a plant receives more light, then it will have a higher rate of photosynthesis. The data supports

Subject Area: Life Science (Biology) Grade Level: 5th/6th Grade Estimated Time: Date: April 6, 2014 Photosynthesis 1. Brief Overview: Starting off this lesson, we will ask the students what they had for dinner the night before. We will write down some of the food on the board for the class to see. We will then ask the class if these are foods that a plant

was not necessary for photosynthesis to occur. Based upon the results, in experiment one the hypothesis was not supported and that light is essential and important in the process. In the experiment, the exposed leaf to oxygen showed the presence of scratch. With the shield leaf, with soda lime showed an absence of of starch. This explains the reasoning, on the color change with Plant A because starch was present. Meaning, without sunlight (the energy source) photosynthesis will not be able to occur

In order to competently compare photosynthesis and semiconductor-based solar cell's production of electricity i.e. solar cell electricity, they both must be defined. Photosynthesis is defined as, (Biology Online, 2010) “The synthesis of complex organic material using carbon dioxide, water, inorganic salts, and light energy (from sunlight) captured by light-absorbing pigments, such as chlorophyll and other accessory pigments.” According to Thomas gale, ( Thomas gale, 2006), solar cells create electrical

according to science eukaryotes came to existence because we evolved from prokaryotic cells. At the beginning of time, the only inhabitants of earth were microbes. Aerobic cellular respiration and oxygenic photosynthesis both play a big role in our evolution. Cellular respiration is a process that mostly takes place in the mitochondria where cells break down food and turn in it into adenosine triphosphate(ATP), or in more simpler terms, energy for the cell. Although cellular respiration can do either

light affect photosynthesis. This was done by placing portions of a green plant in a bromothymol blue solution and observing the colour changes that occurred. It was determined that plants exposed to light produce far more oxygen than those placed in a dark environment. This confirms the hypothesis that oxygen is necessary for continued photosynthesis.

Photosynthesis Lab 8 Section 022 Kaileen Savage Tanushree Majumber Introduction “Photosynthesis is a biochemical process for building carbohydrates using energy from sunlight and carbon dioxide taken from the air”, (Morris, J. (2016) Biology How Life Works. New York, NY.). It is a system that uses plants and specific algae to synthesize molecules from both water and carbon dioxide. The oxygen we breathe and the food we eat is fueled by photosynthesis because it is an energy source

wavelength on the rate of photosynthesis. The effect of different coloured light will also be explored through the rate of photosynthesis. The report will also determine the colour of light that produces the highest rate of photosynthesis. Introduction: The process in which plants, algae and some bacteria use energy form sunlight to produce glucose from carbon dioxide and water is Photosynthesis. Oxygen is also formed as rate of photosynthesis. The faster the rate of photosynthesis, the more glucose produced

important in the process of photosynthesis. Light is not only important in the light- dependant stage but the light-independent stage wouldn’t occur without light because light is changed from light energy to chemical potential energy and is carried out through the ATP and NADPH which takes the energy to the Calvin stage where that energy is used to make other organic compounds that we may be able to use like glucose. I also learned that light helps in the breaking down process of chemical compounds
