Characteristics of angiosperms:
(i) The seeds produced by these plants are enclosed within the fruit.
(ii) They are also called flowering plants because they produce flowers and their reproductive organs are aggregated within the flower.
(iii) Plant embryos in seeds have a structure called cotyledons (seed leaves).
(iv) Endosperm has triploid cells and supplies nutrients to the developing embryo in the seed.
Examples: Pea (Pisum sativum), maize (Zea mays) and wheat (Triticum aestivum)
