Question

Both pteridophytes and bryophytes lack flowers and seeds, yet they are placed in different groups. Explain this classification using their key features.

Answer 1

Both bryophytes and pteridophytes are non-flowering, seedless plants that reproduce through spores. However, they are classified into different groups based on their body structure and vascular tissues.

Bryophytes	Pteridophytes
They lack vascular tissues (xylem and phloem).	They have well-developed vascular tissues (xylem and phloem).
They do not have true roots, stems and leaves.	They have true roots, stems and leaves.
Examples: Mosses and liverworts.	Examples: Ferns and horsetails.

Bryophytes and pteridophytes are placed in different groups mainly because of differences in their vascular tissues and body organisation.
