source of energy forphotosynthesis

Photosynthesis and all associated reactions take place at the molecular level. These microscopic reactions involve several molecules aside from chlorophyll. Some of the other molecules are water (H2O), carbon dioxide (CO2), oxygen (O2), and glucose (C6H12O6). All of the components are necessary and the absence of any one of them causes the entire process to fail. For example, if there is no water available to the plant roots, they will begin to turn brown and die, effectively stopping photosynthesis. Oxygen and glucose are not used in photosynthesis, but are byproducts of the reaction. Oxygen is released into the air, and glucose is stored inside the plant cells.

Photoheterotrophy: use of organic compounds as a carbonsourceduring bacterial photosynthesis

I should point out that both the photo and the synthesis parts of photosynthesis aremultiple step reactions. Quite a number of steps are involved in separating hydrogen andelectrons from oxygen in water. Similarly, quite a number of step are involved in removingoxygen from carbon dioxide and incorporating hydrogen and additional electrons into thecompound. Also, the carbon dioxide is not used to create a new compound as such, butinstead, the carbon is incorporated into existing carbon-containing compounds in a waythat makes them larger than they were before.

Anoxygenic photosynthesis: photophosphorylation in theabsenceof O2

Through the process of photosynthesis, sun light is absorbed by plants and converted into chemical energy. Using that chemical energy, the plants are then able to absorb carbon dioxide from the atmosphere and turn it into food for themselves. A beneficial byproduct of that food production is oxygen, which humans need in order to breathe. Photosynthesis will occur in plants, algaes, and different species of bacteria, and organisms that can perform photosynthesis are referred to as photoautotrophs, meaning they can create their own food. Photosynthesis is vital to life on Earth as it helps maintain normal levels of oxygen in the air which is necessary for survival of most species.

Light from the sun is actually energy, and is advantageous to the Earth in several ways. One of the most important ways is through photosynthesis. Plants absorb the red and blue wavelengths of light energy, and reflect the green wavelength. This is why plants appear to be green; that is the color not being absorbed by the plants.

The photo part of photosynthesis involves the oxidation of oxygen, specifically the oxygen from the water. The photo part provides us with reducing power (in the 4H·) and energy and also oxygen for animals to breathe.

Fundamentally, most eucaryotes produce energy (ATP) through alcoholfermentation (e.g. yeast), lactic acid fermentation (e.g. muscle cells,neutrophils), aerobic respiration (e.g. molds, protozoa, animals) oroxygenicphotosynthesis (e.g. algae, plants). These modes of energy-generatingmetabolismexist among procaryotes, in addition to all the following types ofenergyproductionwhich are virtually non existent in eucaryotes.

Write the number &name of the principle area of photosynthesis.

Plantsuse a process called photosynthesis to make food. During photosynthesis,plants trap light energy with their leaves. Plants use the energyof the sun to change water and carbon dioxide into a sugar called glucose.Glucose is used by plants for energy and to make other substances likecellulose and starch. Cellulose is used in building cell walls. Starchis stored in seeds and other plant parts as a food source. That's why somefoods that we eat, like rice and grains, are packed with starch!

Write the number &name of the principle area of photosynthesis.

Printout A plant is a member of the kingdom Plantae, a living organism that utilizes photosynthesis, a process in which energy from sunlight is converted to chemical energy (food).

Photosynthesis Images - Photos - Pictures - …

In leafy plants, the process of photosynthesis occurs largely in the leaves. Because of this, all the necessary ingredients need to be present in the leaves for the reaction to take place. Carbon dioxide is absorbed into the leaves from the air, water is routed from the roots to the leaves, and sunlight is absorbed into the leaves through chlorophyll. Chlorophyll is a green pigment inside plant cells called chloroplasts - which also have several other structures within them. Chloroplasts are important because they are where photosynthesis takes place.

Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (singular: stoma. plural: stomata)

The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf. This also allows the oxygen produced in photosynthesis to leave the leaf easily.




Carbon dioxide is present in the air we breathe, at very low concentrations. Even though it forms about .04% of the air, it is a needed factor in light-independent photosynthesis.

In higher concentrations, more carbon is incorporated into carbohydrate, therefore increasing the rate of photosynthesis in light-independent reactions.

The processes of photosynthesis and cellular respiration are linked to each other, however, they also differ in a couple of pointers. It is important that one understands this difference.
