Where can I find information on the anatomy or biology of seeds?
For example if I want to know the anatomy (some sort of drawing) of a green bean where can I go to find such information?
Searching Google does little to nothing to describe this process, let alone provide a good picture or drawing. The images of Google do return some results, but they are posts that were made by people on Twitter or Pinterest. Even Google Scholar does not have a lot of research papers on such info.
Seems like the only option is to purchase Text books which cost upwards of $200 each.
