Answer:
Correct Answer: D
Solution:
In bryophytes, the zygote, on germination, produces the gametophyte plant.
It undergoes segmentation to form an embryo.
But the embryo formation and its development to sporogonium and sporophyte are dependent on gametophyte plant as the sporophyte is dependent on the gametophyte for nutrition.
They remain attached organically to the gametophytic plant.
In algae, the zygote is independent and it does form the sporophyte.
