In case anyone was interested, here is a good video explaining the splash cup mechanism of flowering plants that I discussed in class. For some reason on my computer it won't allow me to fast-forward/rewind, so if you want to go back and read something you have to start it over; just pause and it should work fine.
Also, a link to the older article from 1951 can be found here.
On a separate note, the field of 3-D printing is still a bit in its infancy when it comes to the field of medicine/biology, but in recent years there have been some revolutionary advancements, especially with regards to tissue engineering. I highly recommend putting in a bit of independent research on it if you have time--there's some cool stuff being made out there.
