what is photosynthesis?

Answer 1

Photosynthesis (photo=light, synthesis=putting together), generally, is the synthesis of glucose from sunlight, carbon dioxide and water, with oxygen as a waste product. It is arguably the most important biochemical pathway known; nearly all life depends on it. It is an extremely complex process, comprised of many coordinated biochemical reactions. It occurs in higher plants, phytoplankton, algae, some bacteria, and some protists, organisms collectively referred to as photoautotrophs.

Answer 2

Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!

We can write the overall reaction of this process as:

6H2O + 6CO2 ----------> C6H12O6+ 6O2
Most of us don't speak chemicalese, so the above chemical equation translates as:

six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen

Answer 3

Organisms need energy to survive. Some organisms are capable of absorbing energy from sunlight and using it to produce sugar and other organic compounds such as lipids and proteins. The sugars are then used to provide energy for the organism. This process, called photosynthesis, is used by plants and some protists, bacteria, and blue-green algae.

Answer 4

Photosynthesis is the process of production of carbohydrates in the plant system by using solar enery and carbo dioxide with the help by green leaves (chloroplasts)

Answer 5

Photosyntesis is basically the energy a plant gets from sunlight which gives it the color and strenght for it to become a strong tree in future--its actually energy from the sun without which the plants will fade and die-plants need the 3 as u no--sunlight,water and air-all three will fuse it to grow into a healty plant then into a tree

Answer 6

photosynthesis is a process by which the green plants makes starch its food in the presence of the sunlight where carbondioxide is released.

Answer 7

Is the process were the plants catch the sunlight and mixes with water and carbon dioxide to create their own food, not all the plants do so. The result of this process, besides the creation of food if that the plant release oxigen.

Answer 8

Photosynthesis is a process in which plants use sunlight and chlorophyll to synthesise food utilising carbondioxide (co2) and water(H2O).

Answer 9

photosynthesis is defined as process of synthesis of organic compound 4m chlorophyll pigment present in the leaves in presence of sunlight by taking water 4m the soil & CO2 4m the atmosphere.

Answer 10

photosynthesis is the process by which plants prepare their own food
