DENDROLOGY

Detailed explanation-1: -Angiosperms are seed-producing flowering vascular plants. The seeds are enclosed in fruits. These plants are called flowering plants due to the key role of flowers in reproduction. The enclosure of seed for protection and nourishment purposes within the fruit is an adaptation of angiosperms.

Detailed explanation-2: -Flowering plants, or angiosperms, evolved to have vascular tissue, seeds, and flowers. Examples of angiosperms include magnolia trees, roses, tulips, and tomatoes.

Detailed explanation-3: -Vascular plants are also known as tracheophytes. They include pteridophytes, gymnosperms and angiosperms. Non-vascular plants lack a specialised vascular system for transporting water and nutrients.
