Solution

(a) Root hair

Reason: Nodes are the connecting parts of the stem from where the bud arises. The part of the stem between the two nodes is known as an internode. Thus node, internode and bud are associated with the stem except root hair. Root hairs are hair−like outgrowths which arise from the tip of the roots.

(b) Leaf apex

Reason: Calyx, corolla, gynoecium are parts of a flower whereas the leaf apex is a part of the leaf.
