Final answer:
True, angiosperms are both flowering plants and can include vegetables. They are the dominant type of plant species, characterized by their reproductive structures - flowers that produce seeds housed in fruits, which serve to distribute those seeds.
Step-by-step explanation:
The statement about angiosperms being flowering plants is true. Angiosperms are indeed the most dominant form of plant life in terrestrial ecosystems, accounting for about 90 percent of all plant species. These plants are characterized by the presence of flowers and the development of fruit following fertilization. The primary function of the flower, which evolved from modified leaves, is to facilitate reproduction through the protection and production of male (pollen grains) and female gametes (eggs inside ovaries). After fertilization, the ovary walls thicken and mature into a fruit, often bright and attractive to aid seed dispersal by animals, wind, or water. Vegetables are also often considered under the umbrella of angiosperms due to them being parts of flowering plants used for food.
