Hint: Flowering plant ancestors diverged from the common ancestor of all living gymnosperms over 300 million years ago, with the first record of angiosperm pollen appearing around 134 million years ago. The first remains of flowering plants date back 125 million years.
Complete answer:
Angiosperms are types of vascular plants that have stems, roots, and leaves. Angiosperm seeds can be found in flowers. These constitute the vast majority of all plants on the planet. The seeds germinate inside the plant organs and grow into fruit. As a result, they are also referred to as flowering plants. Angiosperms are the most advanced and beneficial plant group. They can grow in a variety of habitats as trees, herbs, shrubs, and bushes.
Angiosperm Characteristics:
Angiosperms have a wide range of characteristics. The following are some of the most important characteristics of angiosperms:
- Flowers appear on all plants at some point in their lives. The flowers serve as the plant's reproductive organs, allowing it to exchange genetic information.
- The sporophyte is composed of stems, roots, and leaves.formed into a structure called the flower.
- True vessels in the xylem and companion cells in the phloem comprise the vascular system.
- The ovules are encased in the ovary, which is located at the base of the megasporophyll.
- Angiosperms are heterosporous, which means they produce two types of spores: microspores (pollen grains) and megaspores.
- Within the nucellus, a single functional megaspore is kept indefinitely.
- Diploid sporophytes exist.
- The root system is extremely complex and consists of cortex, xylem, phloem, and epidermis.
Thus, angiosperms are vascular.
Note: Angiosperm stems are composed of seven layers, as illustrated on the right. Flowering plants have more and more complex tissue formation than gymnosperms. The stem's vascular bundles are organized in such a way that the xylem and phloem form concentric rings.
