Cells<span> are </span>small<span> because the ratio of surface area to volume is the most efficient at their size. This is because when you have a lot of </span>small<span> objects </span>vs<span> a few </span>big<span> objects the surface area is much </span>larger<span> in relation to volume.</span>
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)
Answer:
a chain of amino acids makes a protein
<span>a. they did not co-evolve with the natural species and lack natural controls, like predators</span>
Answer:
it is important to view cells under a microscope because cells can change?
False
Explanation:
Cell does not change when viewing under microscope, it is expedient to view under microscope because it is a microorganism that can not be seen with naked rather than with a microscope
