    Hi Miss Estruch, how do roots know where the light source is if there's no light in the soil?

    with gravitropism in shoots, if cell elongates on lower side, then why doesn't this increase in weight cause the shoot to bend downwards?

    Hi Miss, can you explain how this distinguishes from GCSE apart from changing the name of auxin to IAA? Because i want to use this topic in my essay however i can't really see the difference from gcse

    hi miss, i love your videos and they have been helping me so much thank you!! at 5:00 however i dont understand how "IAA inhibits cell elongation causing root cells to elongate more on the lighter side" if it inhibits growth in the root why is it still growing downwards?

    • @juliettecurran3173
      @juliettecurran3173 2 года назад +2

      I think it's because the IAA inhibits elongation of cells in the lower (more shaded) side of the root, meanwhile the cells on the upper (less shaded) side of the root keep elongating so they kind of grow over the lower side, causing it to bend downwards. Im not 100% sure though, if anyone else knows the answer pls correct me haha
