This usually occurs in a dual fusion process known as double fertilization (Figure 2.1). 1985. In higher plants, the seed precursor (ovule primordia) is composed of three parts: funiculus, nucellus and chalaza, generating the latter one (II) or two (OI and II) protective maternal integuments (seed coat, SC). Seeds are a protective structure that lets a plant embryo survive for long periods of time before it germinates. Following is the significance of seed formation: Dependable Method. Dispersal.
