Differentiate between tropic and nastic movements in plants . Give one example of each.

P and Q are two types of plants having weak stems which cannot stand upright on their own. The plants P and Q have organs R and S respectively which can grow towards and support which they happen to touch and wind around that support. It is observed that organ R originated from the leaves of the plant whereas organ S originates directly from the stem of the plant. (a) What is (i) R, and (ii) S? (b) What is the name of growth movement exhibited by the organs R and S? (c) Name the stimulus involved in this case. (d) State whether the behaviour of organs R and S is a tropic movement or a nastic movement. (e) Name one plant like P and another plant like Q.
