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)

PLEASE I DONT UNDERSTAND THIS!! qnq
denpristay [2]

Interesting biology question.

In order to answer this question, I hope you understand what is mitosis: cell division that creates two diploid "daughter" cells that are identical to each other. Gametes, remember, are the reproductive cells (egg cells and sperm).

If human gametes were made by mitosis, which is not true, because gametes are made in meiosis, they would simply be diploid with somatic cells. The two gametes would have 92 chromosomes, as each cell has 46 chromosomes. And after each generation, the number of chromosomes would keep doubling, which would be very weird. Remember that the normal amount of chromosomes that a human being has, is 46. Maybe humans would have mutations if that happened.

Were there many or few vessels serving as conduits between the lungs and the heart? why is this important?
EastWind [94]
True, there are many vessels serving as a conduit<span> between the lungs and the heart. 

The number of the vessel is many because all the carbon dioxide from body need to be released at the lungs. More vessel means more surface area and blood flow rate to do the diffusion of the gas which means increased diffusion rate. This will allow the lung to transfer oxygen and dump carbon dioxide faster.</span>
