Pigments: These are molecules that absorb specific wavelengths (energies) of light and reflect all others. They're like the actual dish part of our satellite dish analogy.
Reaction Center: This is where the photochemistry takes place - it's like the receiver on our satellite dish where signals get converted into usable data.
Antenna Complex: This is a system of chlorophyll molecules in a photosystem which collects light and feeds it to the reaction center - think about it as cables connecting different parts of our satellite dish for signal transmission.
