As a seed grows, there are teenie tiny pieces of nutrients and chemicals around it that needs to collect by chemical reactions, use them and send them to various other cells.
Then it forms a trunk, cells do the job of passing nutritions from the ground up to the leaves that probably use the most nutritions. Then tree gets bigger and bigger, does it still keep on sending foods upwards cell bu cell? Or it deforms and makes a larger pathway (highway) for hte food to go up?
Can we do this? extend the functionality of the cells that we make and make highways at some point of progress? What about origami? Can you increase bandwidth?
