These tools have enabled us to better understand the magnetic field of the sun and individual characteristics of the sun. Pictured above is Galileo Composition of the Sun The radiation that Earth receives from the sun is quite remarkable. The radiation that we receive varies less than 1% over a period of twenty four hours. However this less than one billionth of the radiation given off by the sun.

.... which is the gametophyte generation. The antheridia and the archegonia are developed on the bottom of the prothallus. The archegonia are at the notch of the prothallus and the antheridia are located near the tip.
