Seedless Vascular Plants Questions and Answers
- 1.
Which of the following is not a division of seedless vascular plants?
- A.
Mosses
- B.
Psilophyta
- C.
Fern
- D.
Whisk fern
Correct Answer
A. MossesExplanation
Mosses, belonging to the Bryophyta division, differ from seedless vascular plants due to the absence of specialized vascular tissues. Unlike seedless vascular plants, mosses lack xylem and phloem, hindering efficient water and nutrient transport. Their life cycle relies on spores for reproduction, and they lack the true roots, stems, and leaves characteristic of seedless vascular plants.Rate this question:
