The given diagram shows a Marchantia thallus (liverwort).The function of structure x:
Correct answer: D. Help in vegetative propagation
- A. Provide protection
- B. Provide nourishment
- C. Help in gametes production
- D. Help in vegetative propagation
Explanation
The primary function of structure X is vegetative propagation.A gemma cup is a cup-shaped structure found on the surface of bryophytes (like liverworts and mosses) that produces gemmae. Its function is vegetative propagation as the gemmae are tiny, bud-like structures that are released from the cup to grow into a new, genetically identical plant.So option D is correct.
