ScienceIf in an experiment the stem does not bend towards light but the plant is alive, which process is more likely disturbed?Class 10Control and CoordinationPlant hormonesLevel 18MediumScienceWhy can a high auxin concentration produce different effects in roots and stems?Class 10Control and CoordinationPlant hormonesLevel 18HardScienceA plant receives light from one side, and its stem bends towards that side. What is the most accurate role of auxin?Class 10Control and CoordinationPlant hormonesLevel 18MediumScienceAfter removing the tip of a plant bending towards light, bending decreased. What conclusion follows?Class 10World of LivingControl and CoordinationLevel 17MediumScienceHigh auxin concentration may inhibit growth in roots but promote growth in stems. What conclusion follows from this?Class 10Control and CoordinationPlant hormonesLevel 17HardScienceWhy does a plant bend towards light if auxin collects more on the shaded side of the stem?Class 10Control and CoordinationPlant hormonesLevel 17MediumScienceIf auxin distribution remains equal on both sides, why can bending of the stem in one direction decrease?Class 10World of LivingControl and CoordinationLevel 16MediumScienceWhy is it incomplete to describe phototropism only as bending of a plant?Class 10Control and CoordinationPlant hormonesLevel 16HardScienceWhen light comes from one side, the stem bends towards it. Why does more growth occur on the shaded side?Class 10World of LivingControl and CoordinationLevel 16HardScienceIf a plant receives light from one side and auxin collects on the shaded side, what will happen?Class 10Control and CoordinationPlant hormonesLevel 18MediumScienceHigh auxin concentration may inhibit growth in roots but promote growth in stems. What does this show?Class 10Control and CoordinationPlant hormonesLevel 17MediumScienceCells on the shaded side of a plant stem become more elongated. In which direction will the plant bend?Class 10Control and CoordinationPlant hormonesLevel 17MediumScienceIf auxin distribution is artificially kept equal in a plant why may stem bending reduce even with one sided light?Class 10Control and CoordinationPlant hormonesLevel 16HardScienceWhy is phototropism in plants called a growth based response?Class 10Control and CoordinationPlant hormonesLevel 16MediumScienceA plant stem is given light from one side and it bends towards the light. What is the correct reason for this bending?Class 10Control and CoordinationPlant hormonesLevel 16MediumScienceHow does auxin help in phototropism in a stem?Class 10World of LivingControl and CoordinationLevel 18MediumScienceIf light falls on a plant stem from one side only then towards which side will the stem bend?Class 10Control and CoordinationPlant hormonesLevel 18MediumScienceIn which example is chemical coordination clearly seen?Class 10World of LivingControl and CoordinationLevel 17MediumScienceIf the tip of a plant is cut off, why may phototropism become weak?Class 10World of LivingControl and CoordinationLevel 17MediumScienceA plant was given light from one side. After some time the stem bent towards light. What is the main reason for this bending?Class 10World of LivingControl and CoordinationLevel 17Medium
