WebMature seeds dry out and slow down the metabolic activity of the embryo. This allows the seed to germinate under favourable conditions, or remain dormant until that happens. Fruit As the ovule forms the seed, the walls of the ovary become the pericarp, or walls of the fruit. WebDuring the development of the embryo sac inside a flowering plant ovule, the three cells at the chalazal end become the antipodal cells. Chalazogamy [ edit] In most flowering plants, the pollen tube enters the ovule through the micropyle opening in the integuments for fertilization (porogamy).
