Q.
Which one of the following is not related to other three?
Sexual Reproduction in Flowering Plants
Solution:
Antheridium is a male structure and the other three
archegonium, oogonium & ovule are female parts. An
antheridium is a haploid male reproductive structure
producing gametes, occurring in ferns, mosses, fungi and
algae. Archegonium is the female, egg-producing
reproductive structure on the gametophytes of non - flowering land plants. The archegonium is comprised of
an oogonium surrounded by protective layers of thick walled pigmented cells. In seed plants, ovule is the
structure that gives rise to female reproductive cells
