Detailed explanation-2: -Today, angiosperms represent nearly 90% of all extant plant species and dominate most of Earth’s terrestrial ecosystems.

Detailed explanation-3: -As vascular plants, gymnosperms contain two conducting tissues, the xylem and phloem. The xylem conducts water and minerals from the roots to the rest of the plant and also provides structural support.

Detailed explanation-4: -Angiosperms are seed-producing plants, also known as flowering plants.
