is pressure flow the same of as Mass flow?

it was really clear and helpful .thanks

[jonasfanfrmpakistan]

Can anyone please send me a message explaining how the food is transported from phloem cells to the sinks by ACTIVE TRANSPORT?

Active transport means that movement of molecules from a higher concentration to lower. there is nothing in the sinks and the phloem cells have everything so isnt it the other way around? Please help me out! I have an exam coming up!

Note: This hypothesis has been granted a state of theory.

@Swordsman0

osmosis is a type of diffusion so....

we can also call it water diffusion.=)

[Swordsman0]

Movement of water from the xylem to phloem is called Osmosis, not diffusion.

@EduardoMalheiro123 no a hypothesis is just something that can be subject to change if new information comes it is a hypothesis
