The correct answer is C. Is the dominant plant.

The prothallus of a fern is actually the gametophyte generation, which is the smaller, non-dominant phase of the fern life cycle. The dominant phase is the sporophyte generation, which is the larger, more visible plant.

The other options are correct:

- A. Is flattened heart-shaped structure: The prothallus is typically a small, flat, heart-shaped structure.
- B. Is green because its cells contain chloroplasts: Prothallus cells contain chloroplasts, which allow them to photosynthesize.
- D. Bears the s*xual organs: The prothallus produces the s*xual organs (antheridia and archegonia) responsible for fertilization.
- E. Is attached to the ground by numerous rhizoids: Prothallus is attached to the ground by small, thread-like structures called rhizoids.

Note: The prothallus is a critical stage in the fern life cycle, but it's not the dominant phase. The dominant phase is the sporophyte, which produces spores for reproduction.

sporophytes are dominant phase of fern

Unlike the spores (indusium and sorus), it is a precursor to the plant itself, that is, it develops into a mature after some growth processes.
