DENDROLOGY

Detailed explanation-1: -Angiosperms evolved during the late Cretaceous Period, about 125-100 million years ago. Angiosperms have developed flowers and fruit as ways to attract pollinators and protect their seeds, respectively. Flowers have a wide array of colors, shapes, and smells, all of which are for the purpose of attracting pollinators.

Detailed explanation-2: -The higher diversity of angiosperms is due to their wide adaptability in terrestrial ecosystems. Angiosperms, are also known as flowering plants and having seeds enclosed within their fruit. Whereas gymnosperms have no flowers or fruits and have naked seeds on the surface of their leaves.

Detailed explanation-3: -Pollinating insects became major players in the evolutionary history of angiosperms assisting them in and explosion of diversity around 100 million years ago. Today, angiosperms dominate the plant world with an estimated 300, 000-500, 000 species, compared to a mere 1, 000 species of gymnosperms.
