Photosynthesis - A Process of Organic Compounds

in Process

Photosynthesis is nothing but a process to convert Carbon dioxide into organic compounds it means conversation of light energy into chemical energy and especially powerful in the bond of sugar.

Plants needs light energy, carbon dioxide and water to make sugar, so photosynthesis process is strong in link of sugar, Photosynthesis occurs in algae, plants and many spices of bacteria, but this process won't take in Archea and releases waste product like oxygen. The process of photosynthesis takes place especially by green pigment chlorophyll in the chloroplasts.

Photosynthesis is very important for life on earth, and even to maintain the standard level of oxygen in the atmosphere, as a source of energy directly almost all living things depends on photosynthesis. In some way the eventual source of energy in their food.

Photosynthesis mainly take place in plant leaves, but not a bit occurs in stems, etc, upper and lower epidermis, the stomates, the mesophyll, and the vascular bundle ( veins) are the parts of typical leaf.

The Photosynthesis process does not occur in upper and lower epidermal cells because the epidermal cells do not have chloroplast. So they serve as principally as safeguard for the rest of the leaf. Stomates are holes which occur mainly in lower epidermis and they take in carbon dioxide in and release out oxygen. The veins or vascular bundles in a leaf are part of the plant's transportation system such as carrying nutrient and water around the plant as they need. The photosynthesis takes place in mesophyll cells, because they do have chloroplast Photosynthesis may occur in different ways in different species and several facial expressions remains same for all time.

For example, the process starts when energy from light absorbed by proteins called photosynthetic reaction centers and it contains the green pigment called chlorophyll, these proteins are detained with in plants organelles called chloroplasts, while in bacteria they are entrenched in the plasma membrane, in the form of adenosine triphosphate (ATP) some of the light energy gather by chlorophyll is stored, then the remaining energy used to remove electrons from a substance like water, then these electrons are used in the reactions to convert carbon dioxide into organic compounds, a sequence of reactions in plant, algae and cyanobacteria called calvin cycle.

But some different kinds of reactions are found in some bacteria's like Reverse Krebs cycle reaction found in chlorobium and it is a range of bacteria. And a number of photosynthesis organisms have adaptations that store carbon dioxide or focus, and this helps to reduce an excessive process called photorespiration process and this can consume in photosynthesis to produce sugar.
