Design an experiment to demonstrate hydrotropism? With diagram.
Answers
Answer:
Aim : To design an experiment to demonstration hydrotropism.
Apparatus : Trough with perforated base, saw dust, water, seeds of pea/gram wooden support.
Procedure : Take a trough with perforated base. Fill it with saw dust. Moisten the same. Sow several seeds of Pea or Gram. Place the trough in slanting position by means of a wooden block. Keep the saw dust moist by sprinkling water at intervals. Observe after 2-3 days.
Observations : As the radicles come out the perforations. They come out of the pores and hang downwardly for some time under the influence of gravity. However, after some growth they bend back and enter the perforations to reach moist saw dust in complete disregard of gravity.
Inference : Bending of radicles back into moist saw dust is hydrotropic movement. It occurs despite being against the force of gravity.
