As humans one of the ways we tend to learn is through visuals which drawing

is a part of so through drawings one can give form to what one learns. Imagine having an idea of what a plant cell looks like on a drawing book even without viewing it yet under a microscope, it is very possible to give a description of it based on the image seen

Everyone can draw relatively, but then some people major in lt and this involves learning certain skills to aim at perfection.

Those artists who are only famous from other people's drawing skills can become better if they allow themselves to. Remember, while some are gifted artists, some can become good artists through practice.
