Bryophyta show an advancement over algae in:-

Detailed Solution for Test: Plant Kingdom- Bryophytes (April 9) - Question 3
Solution
Haploid gametophyte is the dominant phase in algae while sporophytic generation is mostly represented by diploid zygote. With the colonization of land by plants, sporophyte generation became more developed and long-lived as compared to the gametophyte. Bryophytes have little larger and long-lived sporophyte than green algae. Bryophytes have less developed sporophyte which is dependent on gametophytic generation but parasitism is not an advanced character. Meiosis in zygote just after karyogamy is referred to as zygotic meiosis; it is a characteristic feature of thallophytes only not of bryophytes. Thus, the correct answer is A.
