photosynthesis?

Question

what is photosynthesis

Answer 1

8 word def: the process where light is turned into energy

simple def: the process (that takes place in the chloroplasts of plant cells) in which light + carbon dioxide + water turns into oxygen and sugars.

Detailed def:
(Light Dependent Reaction) Light enters a plant's chloroplasts and then into a thylakoid membrane. The light causes a chain reaction where an electron becomes "excited" and causes NADP+ to become NADPH and ADP to become ATP. Serperatly, H2O splits into hydrogen ions, oxygen and electrons. Those electrons replace the "excited" electrons that moved through the reaction. Oxygen is the byproduct of this reaction and exits the chloroplast.
(clavin Cycle) CO2 enters the stroma(empty space) of the chloroplast. Here CO2 undergoes many chemical reactions and during which many ATP are turned into ADP and NADPH is turned into NADP+. during the cycle, glucose (sugar) is created.

Answer 2

Humans respire using mitochondria, the food we eat is converted to energy (Adenosine Triphosphate, ATP.) However plants don't eat, but every living thing requires energy. Photosynthesis is the process by which a plant obtains its own energy, because it cannot eat.
Using chloroplasts, a eukarotic plant organelle, can create its own energy. Chloroplasts are like mitochondria. With photosynthesis 6CO2 + 6H2O --> C6H12O6 + 6O2.
Carbon Dioxide + Water --> Glucose + Oxygen. For this reaction to take place, sunlight is essential as the pigment in chloroplasts (called chlorophyll) uses sunlight for the conversion.

Answer 3

it is NOT "the respiratory fuction of plants". Plants have a respiratory function of their own, which is similar to the animal respiratory system. It's like the opposite.

Photosynthesis is the creation of glucose (kinda like sugar) and oxygen from carbon dioxide, water, and light energy.

Respiration is extracting energy from glucose (which plants made through photosynthesis) which may or may not use oxygen.

Answer 4

synthesis of chemical compounds with the aid of radiant energy and especially light; especially : formation of carbohydrates from carbon dioxide and a source of hydrogen (as water) in the chlorophyll-containing tissues of plants exposed to light

Answer 5

It is decribed as the respiratory fuction of plants.
Using CO2 from outside air, water and using their leaves (for the most part) to fuel themselves from the sun and nutrients in the soil.
The waste product just happens to be oxygen.

The sun being the photo part and the production of nutrients from our waste being the synthesis.
