Answer:
There is a great difference between light and scanning electron microscope. The source of illumination is light rays in light microscope while in scanning electron microscope electrons are the source of illumination.
The resolving and magnification power of scanning electron microscope is much greater than that of a light microscope. The magnifying power of a light microscope is 1000X and of electron microscope is 10,00,000X.
In light microscope image is seen through the eyepiece while in scanning electron microscope it is seen on a fluorescent screen. Even small specimens up to 0.1 micrometers can be seen by scanning electron microscope which is not possible to see by light microscope.
Plankton is the organisms that form the base of most open ocean food webs because fish eat plankton and bigger fish like sharks eat the little fish that eats the plankton.
Homozygous is the same heterozygous is different. Such as TT and tt are homo and Tt is heterozygous.
