Light Absorption for Photosynthesis The measure of photochemical efficiency is made by meauring the amount of oxygen produced by leaves following exposure to various wavelengths. It is evident from these absorption and output plots that only the red and blue ends of the visible part of the electromagnetic spectrum are used by plants in photosynthesis.The reflection and transmission of the middle of the spectrum gives the leaves their green visual color.he measured rate of photosynthesis as a function of absorbed wavelength correlates well with the absorption frequencies of chlorophyll a, but makes it evident that there are some other contributors to the absorption.

Photosynthesis and chemosynthesis are both processes by which organisms produce food; photosynthesis is powered by sunlight while chemosynthesis runs on chemical energy. Photosynthesis occurs in plants and some bacteria, wherever there is sufficient sunlight – on land, in shallow water, even inside and below clear ice. Chemosynthesis is the use of energy released by inorganic chemical reactions to produce food.Chemosynthesis is at the heart of deep-sea communities, sustaining life in absolute darkness, where sunlight does not penetrate. Other bacteria make organic matter by reducing sulfide or oxidizing methane.hemosynthesis is the use of energy released by inorganic chemical reactions to produce food.

- For photosynthesis to occur, plants need sunlight, water, carbon dioxide and chlorophyll. Through the process of photosynthesis plants convert light energy into chemical energy. They use this energy to make food which they store as sugars. Photosynthesis occurs in the chloroplasts of the plant, usually in the leaves. The reason that the leaves look green is because of the chlorophyll. Chlorophyll absorbs the red and blue light from the sun, and this is the light the plants use for the process.

How Plants Acquire Their Energy Making energy from the ultimate energy source. Photosynthesis is the process by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel. Here is how it works. The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. Some plants need more sunlight than others, but all need at least a little. Instead of taking in oxygen and breathing out carbon dioxide like animals do, plants take in carbon dioxide from the atmosphere.

- Answer 1: The purpose of photosynthesis is to convert the energy in photons (the infinitesimally small packets of energy that make up light) into the chemical bonds of sugar molecules. Plants (and animals that eat plants) can then store the energy and get it back out when they need it by breaking those chemical bonds.

- The electromagnetic energy of sunlight is converted to chemical energy in the chlorophyll-containing cells of photosynthetic organisms. In eukaryotic cells these reactions occur in the organelle known as the chloroplast. In the chloroplast, chlorophyll is the pigment that absorbs the sunlight. Chlorophyll is typically packed into stacks of membranes (called grana); it is in the grana where some of the sunlight is absorbed.

Photosynthesis Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration.tages of photosynthesis. When chlorophyll a absorbs light energy, an electron gains energy and is 'excited'. The excited electron is transferred to another molecule (called a primary electron acceptor). The chlorophyll molecule is oxidized (loss of electron) and has a positive charge.

Photosynthesis The action spectrum of photosynthesis is a graph showing the rate of photosynthesis for each wavelength of light. The rate of photosynthesis will not be the same for every wavelength of light. The rate of photosynthesis is the least with green-yellow light (525 nm-625 nm). Red-orange light (625nm-700nm) shows a good rate of photosynthesis however the best rate of photosynthesis is seen with violet-blue light (400nm-525nm).

Comparison of Photosynthesis and Cellular Respiration How are photosynthesis and cellular respiration related to each other? Photosynthesis occurs in plants; cellular respiratory occurs in animal life forms. Both processes are used to harvest energy through electron transport. Scientists compare the processes of photosynthesis and respiration by studying the redox reactions present in both processes. Both release energy through the synthesis of ATP. However, redox reactions in photosynthesis and respiration occur in opposite directions.

Photosynthesis Carbon dioxide is converted into sugars in a process called carbon fixation. Carbon fixation is an endothermic redox reaction, so photosynthesis needs to supply both a source of energy to drive this process, and the electrons needed to convert carbon dioxide into a carbohydrate.y comparison, solar panels convert light into electric energy at an efficiency of approximately 6–20% for mass-produced panels, and above 40% in laboratory devices. Photosynthesis measurement systems are not designed to directly measure the amount of light absorbed by the leaf.

- Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities.owever, not all organisms that use light as a source of energy carry out photosynthesis, since photoheterotrophs use organic compounds, rather than carbon dioxide, as a source of carbon. In plants, algae and cyanobacteria, photosynthesis releases oxygen. This is called oxygenic photosynthesis.
