Someone please explain photosynthesis to me
AysviL [449]

Answer:

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

things needed to carry out the photosynthesis:

  • Chlorophyll. Chlorophyll, the pigment in plants that makes them green, is essential to the photosynthetic process.
  • Sunlight. The process cannot work without an energy input, and this comes from the sun.
  • Water
  • Carbon Dioxide.

The process of photosynthesis is commonly written as:

6CO2 + 6H2O → C6H12O6 + 6O2

This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll into a sugar molecule and six oxygen molecules, the products.
