    Does anyone know why auxins inhibit growth in the roots but promote it in the shoot?
    Or why auxins settle on the shaded side?

    • @raniabenamer1283
      @raniabenamer1283 4 роки тому +5

      In a stem, the shaded side contains more auxin and grows longer, which causes the stem to grow towards the light. The plant does NOT bend towards the light. It grows because the auxin causes the cells to elongate on the shaded side, so this side grows more. ... Auxins have the opposite effect on root cells
      This is the answer for the second question

    Is it that the auxins cause cells to grow faster/slower or, to elongate/not elongate? These terms are not necessarily synonymous.

    • @emeco8678
      @emeco8678 3 роки тому +1

      Auxin works oppositely in roots compared to shoots/stems, so auxin inhibits growth in roots on the shaded parts pushing the root back down because the lighted side has less auxin, growing faster.

      @Skashoon 2 роки тому

      @@emeco8678 Remember geotropism. So in the case of the roots, it isn’t light induced, it’s gravity induced. Therefore roots grow downwardly.
