Observe the following figures and identify the structures or parts labelled as P, Q, R, and S.

Step-by-step solution

P = Archegoniophore(the stalk or other outgrowth of a prothallium upon which archegonia are borne), Q = Gemma cup (The gemma cups are cup-like structures containing gemmae), R = Antheridiophore (In bryophytes, the antheridium is borne on an antheridiophore, a stalk-like structure that carries the antheridium at its apex), S = Capsule (a capsule is a type of simple, dry fruit produced by many species of flowering plants).
