The electrons in the electron sea absorb and re-emit the light.
Light causing electrons to be released from the surface of a metal.

When the light waves strikes an object and bounces off

The electrons absorb the light energy, which excites them.
regular reflection
The photoelectric effect is based on two principles. 1. The intensity or brightness of the visible light (number of photons): The higher the intensity (larger number of photons) determines the number of electrons that are released from the surface material. 2. The frequency of visible light (wavelength): The higher the frequency a beam of light has when it strikes the surface determines the speed (kinetic energy) of the electrons that are ejected from the material. This is independent from light intensity. The higher the frequency of the light, the higher the energy of the electrons emitted, and thus, the higher the current of the circuit.

When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
When light energy strikes a leaf then chlorophill (a) present in leaf absorb that light energy . By use of that energy photosynthesis occurs.
The electrons absorb the light energy, which excites them.
Electrons are replaced with splitting water when light strikes chlorophyll.
Not quite. Remember that electrons are part particles and part waves. Light is given off when an electron drops from one energy state to a lower one. In answer to a different question, and may be the one you ask, When light strikes a phosphor, the electrons in the phosphor absorb energy, and give it off some time later. This is Phosphorescence.
When light strikes a thylakoid, energy is transferred to electrons which cause them to jump to a higher energy level... the electrons are now "Excited". Hope this helps :D
regular reflection
electrons become excited
light strikes the chloroplast.
