What is the movement of hormones like gibberelin, cytokinin and auxin  in plants apoplast or symplastic and passive or active?

 

Elaborate it with your understanding?

Dear student,
Auxin shows polar movements i.e movement in both the direction through xylem or phloem. Polar movement of auxin is now believed to be through parenchyma cells. In cytokinin movement occurs from root to different parts through xylem passively but from shoot towards root occurs through phloem by photosynthesis. Gibberellin translocation occurs through xylem cells, phloem cells and also diffusion. Hormones are moving through apoplastic or symplastic movement.
