The given diagram shows two gametophytes of Marchantia plant.The structure that bears antheridia is labelled as:
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
In Marchantia, the gametophyte is the dominant phase of the life cycle, exhibiting structures known as antheridiophores and archegoniophores. Antheridia, the male reproductive organs, are borne on antheridiophores. In the diagram, the structure labeled D is identified as the antheridiophore, hence it bears the antheridia.so option D is the correct option.
