Answer:
The correct answer will be- Pteridophytes
Explanation:
The plant kingdom is divided into many divisions which are distinguished on the basis of unique characteristics present in them. The main plant groups are Thallophytes, Bryophytes, Pteridophytes, Gymnosperms and Angiosperms.
The plant group which is characterised by having dominant sporophyte, no seeds, presence of xylem and the flagellated sperms is known as the Pteridophytes.
The pteridophytes are the vascular plants with no seed production and contain flagellated sperm which help the sperm to swim to reach the female reproductive structure.
Thus, pteridophytes are the correct answer.
