When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.
- It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll. 
- An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules. 
- An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
- Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.

Answer:
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.
