Polyembryony in Angiosperm Seeds — NEET Biology

Which of the following statements concerning post-fertilisation changes in flowering plants are correct? S1: In angiosperms, the seed is the final product of sexual reproduction, forming inside fruits from the maturation of the ovule. S2: Albuminous seeds, like pea and groundnut, retain a part of the endosperm as it is not completely used up during embryo development. S3: The wall of the ovary develops into the pericarp, while the integuments of the ovule harden to form tough protective seed coats. S4: Parthenocarpic fruits, such as papaya, are generally seedless and are the result of fruit development without fertilisation. S5: In false fruits like apple and strawberry, the thalamus contributes to fruit formation, and their development occurs typically after fertilisation.
