Process of photosynthesis essay

All organisms depend ultimately upon green plants as a source of organic nutrients. This process occurs whenever radiant energy is received by chlorophyll molecules.

Process of Photosynthesis Uploaded by colakid on Oct 30, Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose.

In so doing, photosynthesis provides the basic energy source for virtually all organisms.

Process of photosynthesis essay

An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend. Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. These organisms are veritable sugar factories, Process of photosynthesis essay millions of new glucose molecules per second.

Plants use much of this glucose, a carbohydrate, as an energy source to build leaves, flowers, fruits, and seeds. They also convert glucose to cellulose, the structural material used in their cell walls.

Most plants produce more glucose than they use, however, and they store it in the form of starch and other carbohydrates in roots, stems, and leaves. The plants can then draw on these reserves for extra energy or building materials.

Each year, photosynthesizing organisms produce about billion metric tons of extra carbohydrates, about 30 metric tons for every person on earth. Photosynthesis has far-reaching implications. Like plants, humans and other animals depend on glucose as an energy source, but they are unable to produce it on their own and must rely ultimately on the glucose produced by plants.

Moreover, the oxygen humans and other animals breathe is the oxygen released during photosynthesis. Humans are also dependent on ancient products of photosynthesis, known as fossil fuels, for supplying most of our modern industrial energy. These fossil fuels, including natural gas, coal, and petroleum, are composed of a complex mix of hydrocarbons, the remains of organisms that relied on photosynthesis millions of years ago.

Thus, virtually all life on earth, directly or indirectly, depends on photosynthesis as a source of food, energy, and oxygen, making it one of the most important biochemical processes known.

Plant photosynthesis occurs in leaves and green stems within specialized cell structures called chloroplasts. One plant leaf is composed of tens of thousands of cells, and each cell contains 40 to 50 chloroplasts. The chloroplast, an oval-shaped structure, is divided by membranes into numerous disk-shaped compartments.

These dislike compartments, called thylakoids, are arranged vertically in the chloroplast like a stack of plates or pancakes.

Photosynthesis

A stack of thylakoids is called a granum, the grana lie suspended in a fluid known as stroma. Photosynthesis is a very complex process, and for the sake of convenience and ease ofPhotosynthesis involves a complex series of reactions, some of which take place only in the presence of light, while others can also be carried out in the dark.

(1) Light or photochemical reactions. (2) Dark reactions. Photosynthesis Essay is provided by US essay writers. Photosynthesis is the process through which green plants and other specific living organisms utilize light energy to convert water and carbon dioxide in to simple sugars.

Through photosynthesis, green plants are able to manufacture their own food which is essential for their growth. Process of Photosynthesis Essay Words | 6 Pages Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules.

The Process of photosynthesis is one of the most popular assignments among students' documents. If you are stuck with writing or missing ideas, scroll down and find inspiration in the best samples.

Process of photosynthesis is quite a rare and popular topic for writing an essay, but it certainly is in our database. The process of photosynthesis in plants is based on two reactions that are carried out by separate parts of the chloroplast. The light reactions occur in the chloroplast thylakoid membrane and involve the splitting of water into oxygen, protons and electrons.

Process of Photosynthesis Photosynthesis is process by which plants containing chlorophyll make carbohydrates from water and carbon dioxide in the air in the presence of light.

Green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose.4/4(1).
