<span>Active transport works to conserve homeostasis. When cells are doing something they typically receive a signal causing channels to open, which in turn lets in a flood of molecules down their chemical gradients. Hope this answers the question.</span>
I think its because so the plants can absorb more nutrients from the soil while being sturdy and wide so when the plant gets snowed on it doesn't break<span />
