solve the question

Dear student,

A- Archegonia is a structure which bears the female gamete in gametophytic phase of bryophytes, pteridophytes and gymnosperms. Since none of these plants bear fruits, hence the statement is true.

B. Embryophytes or land plants consist of Bryophytes, Pteridophytes, Gymnosperms and angiosperms. Whereas, non embryophytes include members of Cyanophyta(blue- green algae) and Chlorophyta (green algae). Here, we observe diplontic life cycle in case of Cladophora . Whereas, we also observe haplo-diplontic life cycle in some green algae like Ulva. Hence the statement is false.

C- Spirogyra contains a free living gametophytic phase. Sporophytic generation is represented by a one celled zygote and is not free living. Hence the statement is true.

Thus, the correct option is 2- True, False, True.
