Explanation:
Detailed explanation-1: -What evolutionary development allowed plants to grow tall? The polymer lignin strengthens the xylem and phloem, giving the plant more support and allowing it to grow taller.
Detailed explanation-2: -More than 80% of today’s fern species are classified as polypody ferns; the current class name derives from this group name. According to recent genetic analyses, these are the most evolutionarily advanced ferns, and they may have arisen after the appearance of the angiosperms.
