Photons create electrons in two senses. In the first sense, they don't really create electrons but eject them: from a surface in the photo-electric effect or from atoms or molecules in photo-ionization. Observing the photo-electric effect was a key part of discovering quantum mechanics.
In the second sense, an electron is created together with its anti-particle, a positron, when the photon collides with another particle. Particle-antiparticle creation requires a lot more energy than "photo-ejection". This is conversion of energy into matter, in this case matter with a rest mass of just over a million electronvolts (in mass-equivalent units according to Einstein's E=mc^2). So the photon (and target particle) need to have kinetic energy of that amount for electron-positron pairs to be created.

How can you can increase or decrease the energy possessed by electrons?
Electrons can absorb photons and gain energy, and they can emit photons and lose energy.
Is light microscopes use beams of electrons to produce magnified images?
No, a light microscope uses focused light (photons) to produce a magnified image. An electron microscope uses beams of electrons to create a magnified image.
Can you give some evidences that light is a particle?
Photons interact with matter as a particle; for example, photons can be absorbed and emitted by electrons.
Do photon have a greater energy than electron?
No. A photon has no rest mass an electron has mass.
What absorbs photons?
Matter absorbs photons. Electrons in quantized harmonized orbits of the same energy level as the photon absorp it.
Do photons conduct electricity?
No. Electricity is the movement of electrons, and photons have no electrons to move. Photons are the gauge particles for the electromagnetic force, but that's a different concept.

How do electrons gain in energy in photosystem 1?
they absorb photons from sunlight
Why electrons are used for the excitation in the argon ion lasers though light travels faster than the electron?
High energy electrons are much easier to create than high energy photons.
Where do electrons get their energy in photosystem I?
From energy in photons
Are electrons moving through space called light?
Electrons are very small, and have very small mass, but they are not visible light (photons).
Where do electrons get their energy in photosystem II?
From energy in photons
How do electrons gain energy in photosystem I?
They absorb photons.

What is the difference between photons and electrons?
Photons have no charge, no rest mass and travel at the speed of light throuh a vacuum. Electrons have a charge of -1, have rest mass and are part of atoms.
