What cellular structures can be observed with the aid of light microscopy and electron microscopy?​
Serjik [45]

With a light microscope one can view the nucleus and endoplasmic reticulum, large vacuoles etc

The resolution of a light microscope is dependent on the wavelength of light that is the main beam of illumination. Light has approximately 0.4 um (UV)- 0.7um (Infrared) wavelength. Organelles smaller than about 0.5 um will be difficult to discern with a light microscope.

With an electron microscope one can view, in addition, even the ribosomes and mitochondria, chromosomes, tubules etc.

An electron microscope can discern very minute details of a cell. This is because its resolution is dependent on the very small wavelength of a beam of electrons which is approximately 0.002 um (about 10,000 times powerful than a light microscope)

La aleta de una ballena y el brazo del ser humano, sucede lo mismo que en el caso anterior. En el caso de la aleta de la ballena, es como la aleta del pez. En cuanto al brazo del ser humano permite realizar movimientos que contribuyen al desarrollo de sus funciones, como por ejemplo, agarrar distintos elementos. La pelvis reducida de los cetáceos no tiene actualmente ninguna función.

Explanation:

La pata de un pato es una extremidad que por su estructura le permita nadar perfectamente. En cuanto a la aleta de los peces y ballenas, es una parte de estos animales formada por tejido conjuntivo. Pueden tener distintos tamaños y su principal función no sólo es permitir el movimiento sino también la estabilidad. En cuanto a la pelvis reducida de los cetáceos era algo que tenía sentido en especies de antaño. Durante la evolución, su utilidad de fue perdiendo, como podría mencionarse el ejemplo en los humanos de las muelas de juicio.
