AIIMS 2017 Botany Bryophytes MCQ Question

In bryophytes, the zygote undergoes mitosis, not meiosis, to develop into the sporophyte, which is a diploid structure that remains attached to and dependent on the gametophyte for nutrition. Option A is correct as the gametophyte is the dominant phase of the life cycle, while option B is also accurate since fertilization requires water (H₂O) for sperm motility. Option D is true because the sporophyte relies on the gametophyte for sustenance, illustrating the interdependence of these two phases in bryophyte reproduction.
