    I don't think you mentioned it, but can you explain the role of Potassium Ions in opening and closing the Guard Cells.

      Hello,
      They lower the water potential so that water enters the guard cells by osmosis making the cells turgid, so they bend and the stomata open.

    I am in 10 but can understand this easily .Doubt-if a variation arises in a population such that some organism are of different colour than their parent generation.Now,my question is - can they interbreed (i mean parent population with some different colour and their progeny having different colour can interbreed or not please give reason)
    Thanks

      Hello,
      It would depend on whether the variation affected reproduction or not.

    Why do plants have air spaces

      to allow air (O2 and CO2) to move inside the leaf of a plant

    Could you please explain why humidity reduces water potential in plants? Thanks in advance.

    • @MissEstruchBiology
      @MissEstruchBiology  ปีที่แล้ว +1

      If its humid surrounding the plant that means there is moist air outside, which means a less negative water potential. This decreases the water potential gradient between inside and outside of the plant
