Phloem pressure flow ho, it's like the plant's own dabba system, sending sugars from the leaves down to the roots and fruits. It works because sugar is loaded into the phloem tubes in the leaves, which pulls in water and creates a high pressure that pushes the sap flow to where it's needed.
I always picture it like my mother's stainless steel tiffin carrier—the sweet stuff from up top gets packed and sent down to us. My studying under that fan teaches me that real flow needs a pressure to push it, just like my notes won't move from my desk to my brain without the pressure of the coming exam!
