Aug 20, 2020 · What are some unique characteristics of angiosperms? Angiosperms are flowering plants, they have very complex root systems, can have double and triple fusion, and fertilization takes place by pollination. 2. How many carpels are in the lily? How many stamen? The flower had three carpels and six stamen. 3.
Flowering plants, often known as angiosperms, reproduce in a sexual manner. Plant reproduction is primarily centered on the flower, which contains both male and female gametes. Although certain components of a bloom are sterile, they all help in the reproduction process. Pollination is an ecological activity that all blooming plants engage in.

All angiosperms are comprised of stamens which are the reproductive structures of the flowers. They produce the pollen grains that carry the hereditary information. The carpels enclose developing seeds that may turn into a fruit. The production of the endosperm is one of the greatest advantages of angiosperms.Nov 28, 2019

SummaryFlowers, the major innovation of the angiosperms, are organs of sexual reproduction. Angiosperms have reduced pollen to 3 cells, allowing more efficient pollination and fertilization. ... Additional characteristics of angiosperms relate to vascular tissue, seeds, and dispersal.Dec 11, 2015
So, roots and seeds are not the characteristic features of angiosperms. Hence, the correct answer is Option A. Note: Although gymnosperms and angiosperms differ in seed structure and presence of flowers, both have many similarities as well.
Angiosperms have their seeds in a "container," fruit, a major reproductive innovation. The seeds develop from the ovules as the fruit develops from the ovary. Double fertilization maximizes resource use efficiency by ensuring that only fertilized seeds are provisioned.
Features of Angiosperms All angiosperm plants have the characteristic vascular bundle with the xylem and phloem tissues for conduction of water, minerals, and nutrients. The plant body is well differentiated with a well-developed root system, shoot system and leaves.
Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves.
