Plants that evolved vascular tissue are more advanced than plants without vascular tissue. most importantly, possession of vascular tissue enabled plants to
a. reproduce via spores
b. use photosynthesis
c. have smaller root systems
d. grow talle

The correct answer will be option-D

Explanation:

The evolution of vascular tissues in plants from non-vascular plants was an adaptive feature to survive in the terrestrial environment.  The group of plants in which vascular tissues evolved and developed is the Pteridophytes which contained stellar organization of the vascular bundles.

The pteridophytes exhibited xylem and phloem which allows the rapid uptake of the water and nutrients from the soil which allowed the growth of the plant and since plants got enough water and nutrients from the soil, they adapted to grow tall so that they can maximize the output of photosynthesis in bright sunshine.

Thus, option-D is the correct answer.

the correct answer is option b
