Question

The characteristic differentiation of pteridophytes from bryophytes is
A. Well-formed stelar system
B. Circinate venation
C. Independent sporophyte
D. All of the above

Answer 1

Hint: Bryophyte plants are small and non-vascular. Pteridophyte plants are the ferns; usually, they lack flowers and seeds. But pteridophytes have vascular bundles.

Complete answer: The best way to solve this question and find out the correct option would be learning the differences (based on the features mentioned above) between the bryophytes and pteridophytes.

Features	Bryophytes	Pteridophytes
Vascular system:	These are non-vascular i.e. do not have xylems and phloems.	They have well-formed vascular bundles.
Dominating part:	They have a dominant gametophytic phase.	These plants have sporophytes as the dominant phase.
Leaf-venation:	They do not have true leaves but have leaf-like structures that are without venation.	The leaves of these plants show circinate type venation.

Additional information: 1. Both Bryophytes and Pteridophytes are land/terrestrial plants.
2. Both possess distinct Gametophytic and Sporophytic generations in their life cycle.
3. Both groups possess heteromorphic alternation of generation.
4. Rhizoids are present in both Bryophytes and Pteridophytes.

So, the correct option is D. All of the above.

Note: Besides the above differences, there are few more significant ones: Bryophytes have stalked antheridia while pteridophytes have sessile antheridia. Bryophytes do not have roots; rather they have rhizoids that help in anchoring. Roots are present in the pteridophytes.
