Long before a deeper understanding of their numerous biological functions, the plant lectins, also known as phytohemagglutinins, were noted for their particular high specificity for foreign glycoconjugates (e.g. those of fungi, invertebrates, and animals). and used in biomedicine for blood cell testing and in biochemistry for fractionation.
Electromagnetic energy is a term used to describe all the different kinds of energies released into space by stars such as the Sun. These kinds of energies include some that you will recognize and some that will sound strange. They include: Radio Waves. TV waves. Radar waves. Heat (infrared radiation) Light.
The Electromagnetic Spectrum. The electromagnetic (EM) spectrum is the scientific name for types of photon radiation. Electromagnetic radiation consists of photons (light particles) that travel in a wave-like pattern at the speed of light. The amount of energy found in these photons forms the various types of electromagnetic radiation in the spectrum, which is expressed in terms of energy, wavelength or frequency.
