Explanation:
The key adaption of angiosperms that allowed these plants to dominate the landscaper is flowers
<h3>What is the most important adaptation of angiosperms?</h3>
Angiosperms initially appeared in the late Cretaceous Period, between 125 and 100 million years ago.
Flowers and fruit were developed by angiosperms to draw pollinators and protect their seeds, respectively.
Flowers come in a variety of shapes, sizes, and scents that are all designed to entice pollinators.
An egg that has been fertilised grows into a seed that is protected by a fleshy fruit.
Throughout the Mesozoic period, numerous contemporary insect groups developed alongside angiosperms, including insect pollinators that supported angiosperm growth; in many cases, flowers and their pollinators coevolved.

Monocots have only one seed leaf inside the seed coat. It is often only a thin leaf, because the endosperm to feed the new plant is not inside the seed leaf. Dicots have two seed leaves inside theseed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant. [Credit to: Monocots and Dicots - The seed site]
