Endosperm is a distinctive tissue in its origin,
Endosperm is a unique tissue in its origin, development and ploidy level. It is a product of double fertilization but unlike the embryo it is triploid and develops into a formless tissue (Bhojwani and Bhatnagar 1999). It is, therefore, an interesting tissue for morphogenesis. Any abnormality in the development of endosperm may cause the abortion of embryo resulting in sterile seeds (Johnston et al. 1980). The endosperm may be totally consumed by developing embryo leading to the formation of exalbuminous (non-endospermous) seeds or when it persists, the seed is called albuminous (endospermous). In albuminous seeds, it is used as a food source which may contain proteins, starch or fats and the embryo can utilize this food during seed germination
