Multiple Choice Seed-bearing plants differ from all other plants in that A. they have only xylem and no phloem. B. they have a gametophyte generation. C. their gametes do not require water for fertilization to occur. D. they have true roots, stems, and leaves.

C. their gametes do not require water for fertilization to occur.

Explanation:

Seed bearing plants are plants that produce seeds. The gametes of seed-bearing plants do no depend on water for fertilization. Fertilization could occur through the transfer of pollen from the male gametophtye to the female gametophyte through animals or wind.

Unlike other plant types like the bryophytes, they rely on water for fertilization. They so have xylem and phloem as well as other plants. They also have stems,roots and leaves like other plants.
