Answer:
Correct Answer: C
Solution:
Thallophytes, i.e., algae and fungi completely lack the formation of embryo.
In bryophytes, the zygote, on germination, does not produce the gametophyte plant.
It undergoes segmentation to form an embryo.
The embryo (diploid) by further segmentation and differentiation gives rise to sporophyte.
The sporophyll obtains its nourishment directly from the parent gaemtophyte to which it is organically attached.
