How does photosynthesis work in a plant?

Answer 1

Any green coloured surface that is exposed to light with photosynthesize.

The same goes for brown coloured surfaces on Kelp,

red coloured surfaces on red algae.

gold coloured surfaces on golden algae

etc etc.

Photosynthesis generally takes place in the chlorophyll of a plant.

Answer 2

Plants use photosynthesis in order to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohyrdates such as sugars and startches.

Answer 3

The actual mechanism is not fully understood, but it is known that plants somehow use energy from sunlight to break apart carbon atoms from carbon dioxide molecules in the atmosphere and combine the carbon with other elements into sugars and other molecules taken from the ground through the plant's roots, water and other air molecules that make the plant grow.

Most of the free oxygen in the atmosphere, which all animal species -- including we human beings -- need for survival has been freed from carbon dioxide atoms through photosynthesis. This makes forests, and photosynthetic life in the oceans, a very important part of keeping earth's carbon dioxide atmospheric content in check. Carbon Dioxide is a greenhouse gas, so if it builds up too much (because we both release too much, and have destroyed too many trees which would otherwise reduce carbon dioxide), effects will be harmful. There is, already, a growing greenhouse effect measurable by not only average global temperatures, but deglaciation from the vast majority of earth's glaciers, including the Arctic ice cap and the Greenland ice sheet. If the greenhouse effect continues to the point that the ice cap over the Antarctic landmass also melts, ocean levels will rise significantly (there has already been a slight rise in average ocean levels due to the current deglaciation; the arctic ice cap disappearing is a troubling sign, but since it is already floating in water will not itself cause much of a change in global sea levels). Carbon Dioxide is also toxic at higher concentrations, and if carbon dioxide builds up to those concentrations, Earth's atmosphere will be unbreathable to us and most species of animal; plants, however, would thrive.

Studying photosynthesis has a number of interesting applications. Notably, the collection and use of solar energy by plants in photosynthesis is much more efficient and robust than the best solar cells that we can manufacture today. No human-built machine is presently capable of matching a single old growth tree's capacity for stripping carbon dioxide of their carbon atoms and releasing free oxygen. Some experiments have successfully created intense but short bursts of carbon-stripping through inducing chemical reactions with the air, but the amount of carbon eliminated and free oxygen released were quite small compared with how much one old-growth tree does throughout its lifetime.

Answer 4

Photosynthesis in plants is the use of energy from sunlight, which produces sugar, to create food. The formula for this is 6H2O + 6CO2 ---> C6H12O6+ 6O2

Answer 5

In the leaves.
