What is the light of photosynthesis? What is the physiological significance of photosynthesis?

Photosynthesis converts light energy into electrical energy, electrical energy into active chemical energy, and active chemical energy is stored in organic matter to provide energy for plants themselves and other organisms in nature. Isn't that amazing? Encyclopedia Knowledge Network is here to test you today! Do you know what kind of light is photosynthetic? What is the physiological significance of photosynthesis? What are the energy changes and material changes in photosynthesis? The following article will give you a detailed introduction.

What is the light of photosynthesis?

Most lighting will work, fluorescent lamps are usually used.

During photosynthesis, plants mainly absorb red-orange light and blue-violet light, which are also present in white light.

What is the physiological significance of photosynthesis?

1. Convert inorganic matter into organic matter. Provide organic matter for plants themselves and other organisms in nature.

2. Convert light energy into electrical energy, convert electrical energy into active chemical energy, and convert active chemical energy into organic matter for storage, thus providing energy for the plants themselves and other organisms in nature.

3. Absorb carbon dioxide and release oxygen, providing oxygen for the entire natural world and keeping the oxygen in the atmosphere in dynamic balance.

Energy and material changes in photosynthesis

The energy change is: active chemical energy is converted into stable chemical energy and stored in formaldehyde.

The material changes in the light reaction stage are: water is photolyzed into oxygen and reduced hydrogen, and ADP is added with phosphoric acid to generate ATP. Light energy is converted into active chemical energy and stored in ATP.

The material changes in the dark reaction stage are: carbon dioxide is fixed into carbon 3 compounds, then reduced into formaldehyde compounds, and ATP is converted into ADP.
