One problem with pesticide application is that if they use spray, it leaves a residue, so if a child or animal were to get in contact with the pesticide and accidentally ingest it, it could injure them.
I knew this at one point but I forgot it
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:
The cell membrane structure is very important because everything alive has cell membranes. The model used to describe the cell membrane is called the <u>fluid mosaic</u> model.
