Question 10. The unique feature of bryophytes compared to other green plants groups is that
  1.    They lack roots
  2.    They lack vascular tissue
  3.    They produce spores
  4.    Their sporophytes is attached to gametophyte
 Discuss Question
Answer: Option B. -> They lack vascular tissue
The unique feature of bryophytes compared to other green plant group is that it contains no xylem for conducting water through the plant, instead it conducts water and nutrients through the leaves. Therefore, these are termed as non vascular terrestrial plants.
