They take over the photosynthetic process for the plant.
One of the main functions lipids do is storing energy. If a person eats excessive amount of food, lipids help store the energy in the form of fat molecules in the body to use later.

The answer is; UV (ultraviolet)
The security pens use UV light to illuminate some marking on an object,such as a watermark, to identify its authenticity or owner. The markings are usually invisible to the naked eye under visible light. The marks are only visible when illuminated with UV light. This is because the marking is made of a fluorescent material that absorbs light of a shorter wavelength (this case UV) and emits a longer wavelength (this case visible light).
