Angiosperm Plants: Mango, blackberry, palm and most of the green plants around us are closed seed flowering plants. These plants have the ovary. The ovules are arranged within the ovary. After fertilization, the ovules turn into seeds and ovaries develop into fruits. For this reason, the seeds of such plants are found hidden within the fruit.
Angiosperm Plants are a seed-bearing plant of the phylum Angiospermophyta, in which the ovules are enclosed in an ovary, which develops into the fruit after fertilization.
Examples: Astragalus, Begonia, Piper, Peperomia etc.
