The answer is diffusion.
Facilitated diffusion is a process by which molecules are transported across the plasma membrane with the help of membrane proteins.
Not necessarily because cells them self don't actually contain cells
A because I learned that last year in science
E=hv is an equation important when dealing with light. E refers to the energy of a photon; h is Planck's constant and v is the wavelength. According to this equation, light particles called photons travels in packets of energy. This is important in pv cells because this is the technology used to harness solar energy which is converted to electricity. The amount of energy should be estimated to know the appropriate material of construction of the pv cell to achieve optimum conditions. In this way, the pv cell could maximize the sun's energy.
This occurs during protein synthesis. This is because the cell continues to protein synthesise, therefore adding to the amount of cells.
I hope this helps.
