Photosynthesis process

Photosynthesis Process {Step by Step – detailed} ☀️☘️

Photosynthesis in plants works by converting the energy of light particles (photons) with the combination of carbon dioxide and water, into functional energy (carbohydrates) that’s being used to fuel the plant’s mechanisms for its growth cycle. A byproduct of photosynthesis is Oxygen, meaning that photosynthesis in plants is the major factory of oxygen on our planet, a factory that keeps us alive.

The process of photosynthesis explained in simple steps:

The process of photosynthesis

  • Step 1

    H2O (water) from the roots and CO2 (carbon dioxide) from the atmosphere, enter the plant’s leaves.

  • Step 2

    Light (photons) from a specific spectrum of the light’s wavelength (mostly blue and red, because green is being filtered out, and that’s the reason why leaves look green to us) hits the pigments in the membranes of the thylakoids. That light splits the H2O (water) into O2 (oxygen).

  • Step 3

    Two electron carriers (Plastoquinone and Plastocyanin) move the electrons between the membranes of the thylakoids, and the electrons move to the enzymes.

  • Step 4

    Photons of light hit the second pigment molecule which allows the enzymes to convert energy (ADP to ATP, and NADP+ converts to NADPH).

  • Step 5

    The ATP and NADPH are used by the Calvin Cycle as a fuel, to convert CO2 into a carbohydrate (sugar glucose) as energy fuel for various mechanisms, such as cellular growth from which trees gain their mass.

Do you know how plants gain their mass?

Many people think that plants, such as trees, gain their mass from the soil and its nutrients. Though, that’s not the case. Plants get their mass from the atmosphere, specifically from CO2 (carbon dioxide), through the Calvin Cycle.

Here’s a video about it:
