How best you can demonstrate the activity about growing roots with suitable diagram?
Answers
Answer:
Hydrotropism is the process of growth or movement of roots towards the source of water. Here is an experiment that is performed to observe the growth of plants when water is present.
Procedure
Take two beakers 1 and 2.
In beaker 1 add moist soil and sow the seeds.
In beaker 2 add dry soil in one part and moist soil in another part and sow the seeds. Also, place a small beaker of water just adjacent to it.
Keep it for some time so that the plants can grow.
Result
It was found that in beaker 1 due to the presence of moist soil, plants will grow normally and roots will be straight.
In beaker 2 it was observed that the presence of water beaker next to its plant grows towards the water as shown in the above figure.
Conclusion
This experiment states that the plants move and grows towards the source of water, hence plants show hydrotropism.
