The question is incomplete as it does not have the options which are:
A) roots. B) spores. C) seed pods. D) chlorophyll.
Answer:
A) roots
Step-by-step explanation:
The vascular plants are evolved from the Bryophytes which are evolved from the algae.
The algae are non-vascular plants and Bryophytes too. The vascular plants developed the vascular tissue to transport the absorbed water and nutrients from the terrestrial surface.
The plants living during the Devonian period possessed the vascular tissue to transport the nutrients but to absorb the nutrients and water, they also possessed the roots.
Thus, Option-A is the correct answer.
