Difficulty: EasyThallophytes, Bryophytes, and Pteridophytes

Which structural feature differentiates pteridophytes from bryophytes?

  1. Presence of vascular tissues (xylem and phloem)Answer
  2. B
    Presence of well-developed xylem and phloem in mosses
  3. C
    Xylem tissue that translocates manufactured food from leaves down to roots
  4. D
    Extracellular saprophytic digestion of dead organic matter

Answer

Presence of vascular tissues (xylem and phloem)
Pteridophytes (such as ferns) are the first group of land plants to evolve vascular tissues (xylem and phloem) for the transport of water, minerals, and synthesized food, whereas bryophytes (mosses and liverworts) completely lack true vascular tissues.

Step-by-Step Solution

1
Analyze the structural characteristics of bryophytes.
Bryophytes (mosses and liverworts) are non-vascular plants lacking true roots, stems, leaves, and conducting tissues (xylem and phloem).
Identifying the baseline transport mechanism in bryophytes.
2
Analyze the structural characteristics of pteridophytes.
Pteridophytes (ferns) are vascular seedless plants possessing specialized conducting tissues (xylem and phloem).
Determining the primary anatomical advancement of pteridophytes.
3
Compare the two plant groups to find the key distinguishing feature.
The presence of vascular tissue (xylem and phloem) is unique to pteridophytes when compared to bryophytes.
Selecting the correct option based on plant division anatomy.
