Transmission electron magnifying lens - The transmission electron magnifying instrument utilizes electrons rather than light. a light magnifying lens is constrained by the wavelength of light. TEMs utilize electrons as "light source" and their much lower wavelength makes it conceivable to get a determination a thousand times superior to with a light magnifying lens. The likelihood for high amplifications has made the TEM a significant instrument in both medicinal, natural and materials research.Compound light magnifying instrument - Microscope with more than one focal point and its own particular light source. There are visual focal points in the bonicular eyepieces and target focal points in a turning nosepiece nearer to the example. To determine the energy of amplification of a compund light magnifying instrument, it's expected to take the energy of the target focal point and duplicate it by the eyepiece which is by and large 10x. Albeit at times found as monocular with one visual focal point, the compound binocular magnifying lens is all the more regularly utilized today. The principal light magnifying lens goes back to 1595, when Zacharias Jansen made a compound magnifying instrument that utilized crumbling tubes and delivered amplifications up to 9X.
Hi the answer is they were from all parts of the world.

Answer:
Seeds are the result of plant reproduction. ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.
