The field of biology was created by people who love to classify/name things. This has resulted in what we have now: A subject where the prerequisite to understanding is the ability to read long passages of text littered with jargon and visualize what that might represent. Even if everyone's reading skills were where they should be, the second part is not a super common skillset.

It's one of the reasons why I work in visualization for life sciences education: I think we're missing out on people who might otherwise make massive contributions to the field because they failed to memorize what the "endoplasmic reticulum" does. Much of biology you don't have to actually remember what things are called in order to understand the processes (at least at a basic level like what a middle schooler might be taught). Once you're exposed to the fascinating complexity of life at that level, for many people it can be interesting enough to build the motivation for the memorization/etc.
