Vascular Plant

관다발식물

Definition

A plant possessing specialized conducting tissues (xylem and phloem) for transporting water, minerals, and sugars.

Detailed Explanation

Vascular tissue was a key evolutionary innovation enabling plants to grow tall and colonize dry land by efficiently transporting water against gravity. The transition from non-vascular bryophytes to vascular plants during the Silurian period drove the colonization of terrestrial environments and transformed Earth's atmosphere, soil chemistry, and food webs. Over 300,000 vascular plant species exist today, dominating most terrestrial ecosystems.
