Explanation

In bryophytes, the zygote, on germination, does not produce the gametophyte plant. It undergoes segmentation to form an embryo. But the mbryo formation and its development to sporogonium and sporophyte are dependent to sporogoinum and sporophyte are dependent on gametophyte plant as the sporophyte is dependent on the gametophyte for nutrition. They remain attached originally to the gametophytic plant. In algae, the zygote is indepent and it does not form the sporophyte.
