The first food they make is glucose but that can later be changed into other food types. The sunlight is absorbed by the green pigment chlorophyll. Carbon hydrates contain the elements carbon, hydrogen, and oxygen as in glucose. The carbon and oxygen could be supplied by carbon dioxide from the air. In addition, the hydrogen could come from the water in the soil.
Introduction: Photosynthesis is the use of sunlight to produce carbohydrates. In order to produce carbohydrates, photosynthesis converts the energy in sunlight to chemical energy in sugar bonds. Photosynthesis takes place in only the green parts of plants, which the green part are chlorophyll pigments. An example of this would be the leaves of a plant. In order for photosynthesis to occur sunlight, carbon dioxide, and water are essential, however oxygen is produced in the process.
Here is a summary of the most important information on photosynthesis: Photosynthesis requires: * carbon dioxide, * water, * light energy, * chlorophyll. Photosynthesis produces: * glucose, * waste oxygen. Photosynthesis is the conversion of: * light energy into, * chemical energy. Photosynthesis is essential for: * growth. Photosynthesis takes place in: * leaves !!!!!
Carbon dioxide and water are the raw materials of photosynthesis. The equation of photosynthesis is: 6CO2 + 6H20 Þ C6H12O6 + 6O2 =========================== Carbon dioxide + water Þ glucose + oxygen Green plants need sunlight. They use the light energy to make a sugar called glucose. Glucose can be turned into another type of sugar called sucrose and carried to other parts of the plant in phloem vessels. Glucose can also be turned into starch and stored.
The 3 features of the leaves are: 1) They are thin and flat to provide big surface area. 2) Te palisade cells near the top of leaves are packed with chloroplasts. 3) Te Guard cell controls the movement of gases going in and out. The four things needed for photosynthesis are: Light energy, Chlorophyll, carbon dioxide and water. The rate of photosynthesis is affected by the following reasons: the amount of light energy, the amount of carbon dioxide and the temperature.
. Photosynthesis is the biological process whereby radiant light is converted into chemical energy, light is absorbed by the chlorophyll, (a green pigment in chloroplast) the light (radiant) energy is trapped by the chlorophyll. Photosynthesis mainly occurs in the leaves because they have chlorophyll. Oxygen is given off as a waste product the process of photosynthesis requires raw materials such as carbon dioxide, radiant energy, oxygen and water. Photosynthesis is the process of making glucose, a carbohydrate that is needed by humans in order to stay sustained with energy.
The reactions need energy and this comes from light. The green chloroplasts allow light to be used as energy and therefore both of these things are like helpers in the reaction. [IMAGE] 6CO2 + 6H2O C6H12O6 + 6C2 Carbon Dioxide Water Glucose Carbon It is important that certain factors are present when the reaction is occurring. We know that these are carbon dioxide, water, light and Water, carbon dioxide and light, along with temperature, all have a particular effect on the rate of photosynthesis. In terms of carbon dioxide the levels in the atmosphere do not really alter very much, but if gardeners wish to increase the rate of photosynthesis then sometimes carbon dioxide is pumped into greenhouses.
And the light – independent reaction takes place in the stroma of chloroplasts carbon dioxide molecules [ CO2 ] are needed during this stage of photosynthesis . CO2 is added to a cycle of chemical reactions to build larger molecules , Energy from the light –dependent reactions is used in the reactions . A molecule of a simple sugar is formed . The sugar, usually glucose [ C6H12O6 ] , Stores some of the energy that was captured from sunlight . In the light – independent reactions there is a series of chemical reactions called the Calvin cycle , the Calvin cycle is when the carbon dioxide [ CO6 ] enters the light independent stage of the photosynthesis and the six carbon dioxide [ C06 ] splits into two groups of three carbon dioxide [ 2CO3 ] .
This photons absorbed through the lumen go through photochemical reduction in which they are absorbed into pigments such as chlor... ... middle of paper ... ...tabolism of these molecules are spontaneous and does not require light to begin. Photosynthesis requires that chlorophyll is present to process light and at the same time is dependent on light therefore would not occur without one or both. It is obvious that they are both reliant on the other, without photosynthesis to produce the oxygen chemotrophs breathe in order to metabolize glucose for energy. Works Cited 1.

Plants need light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll in green leaves. We have been told in class that the four factors necessary for photosynthesis are light, carbon dioxide, chlorophyll and temperature. The factor I decided to test was light because photosynthesis is often called a “light reaction” and I from this I knew light must be vitally essential for the process to take place. The main source of energy during photosynthesis is light.
