A potted plant is growing in a transparent glass jar. In this plant, X and Y are the two growing parts having a lot of meristematic tissue. It is observed that the part X of this plant exhibits positive geotropism but negative phototropism. On the other hand, part Y of this plant exhibits negative geotropism but positive phototropism.
(a) Name the part X of plant.
(b) Name the part Y of plant.
(c) Which part of the plant, X or Y, will exhibit positive hydrotropism?
(d) Which part of the plant, X or Y, can have tendrils on it?
(e) Which phytohormone causes the part X to exhibit negative phototropism?

(d) Which part of the plant, X or Y, can have tendrils on it?
(e) Which phytohormone causes the part X to exhibit negative phototropism?
(a) Root. Because root shows positive geotropism and negative phototropism.
(b) Stem (or Shoot). Because stem shows negative geotropism but positive phototropism
(c) X. Because root exhibit positive hydrotropism and it is X denotes root.
(d) Y. Because stem can have tendrils on it. It is Y denotes stem.
(e) Auxin. Because it is the phytohormone that causes the part X(root) to exhibit negative phototropism.
(a) Root. Because root shows positive geotropism and negative phototropism.
