Answer 1

11. Correct option E: Multicellular diploid and haploid states is called alteration of generatios life cycle.

In alternation of generations, both the haploid and the diploid stages are multicellular, though they may be dominant to different degrees in different species. Plants and some algae have this type of life cycle.

12. Correct option A: Moss , liverworts and hornworts are nonvascular.Bryophytes (liverworts, mosses, and hornworts) are non-vascular plants that appeared on earth over 450 million years ago.

13. Correct option B: Ferns, gymnosperm and angiosperms are tracheophytes.Tracheophytes are commonly known as vascular plant that contains lignified and non-lignified tissues which includes the angiosperm, clubmosses, ferns, horsetails and gymnosperms.

14. Correct option D: Cooksonia is known as the first vascular land plant because it has conductive tissues xylem and phloem.

15. Correct option C: Ferns have flagellated sperm that must swim to the egg formed by the female gametophyte. For this reason, sexual reproduction must happen in the presence of water.
