Green Beans and Bioengineering

My mother insisted that I eat the green beans on my plate, but they were not all that thrilling. She would say that they have vitamins and we know much more now than we did back then about the health benefits of green beans. Interestingly, they have an internal mechanism that loosely resembles one of our own.

 When we have a wound, the blood will clot and the flow will stop (unless someone has a health condition). The Master Engineer also devised something similar for the beans. They need the sap to flow, but if a part is broken, that's where callose plugs come into play. Try to get a disciple of Darwin to evosplain that to you and come away with a satisfactory answer.

When bean plants are bruised or bitten by a caterpillar, what if the valuable sap in the plant’s vascular tubing kept flowing to the injury site, leading to an unrestrained loss of sap? That’s comparable to an injured human or animal losing blood. In humans and animals, injuries are often mitigated by blood clots (coagulation) and/or scab formation. But what about bean plants? Is there no hope against losing sap when internodes or tendrils are broken off or otherwise damaged?
