The first step in polar transport is auxin influx. According
to the model, auxin can enter plant cells from any direction by either of two
mechanisms:
a) Passive diffusion of the protonated (IAAH) form across
the phospholipid bilayer
b) Secondary active transport of the dissociated (IAA–) form
via a 2H+–IAA– symporter
c) Active diffusion of the protonated (IAAH) form across the
phospholipid bilayer
Find out the correct statements of about diffusion of IAA.
