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.
Electromagnetic energy is familiar to most people as light and heat, but it can take many other forms, such as radio waves and X-rays. These are all types of radiation originating from the electromagnetic force, which is responsible for all electrical and magnetic phenomena. The radiation travels at the speed of light in a manner resembling waves. Unlike sound waves, electromagnetic waves do not require a medium through which to move and can travel across empty space.
