Document Summary
Because of light we are able to see colors. Reason being that the color is reflected off the object. The rest of the colors are absorbed by the object. For example green light is reflected off the leaf. The rest of the colors are absorbed by the leaf. A source of energy that sustains all organisms. Provides information about the physical world that surrounds organisms: example: chlamydomanas reinhardtii. One chloroplast that absorbs energy to do photosynthesis. Light sensor in the eye allows the gathering of information (location and intensity of light) Due to the exact distance between the earth and the sun, the sun is able to make energy off of matter in a matter of seconds. Light is the most common part of the electromagnetic spectrum that humans are able to detect with their eyes. The longer the wavelength the lower the energy of photons it contains. Light is composed of photons which is a stream of energy particles.
