The developing embryo passes through different stages such as the proembryo, globular and heart-shaped stages before maturation. Mature dicotyledonous embryo has two cotyledons and an embryonal axis with epicotyl and hypocotyl. Embryos of monocotyledons have a single cotyledon. After fertilisation, ovary develops into fruit and ovules develop into seeds.
Which of the following statements regarding fruit and seed characteristics are NOT correct? S1: Apple and strawberry are examples of false fruits because the thalamus contributes to their edible portion. S2: True fruits are always the result of fertilisation and develop exclusively from the ovary. S3: Parthenocarpic fruits are characteristically seedless and can be induced by the application of growth hormones, but banana is not a natural example of such fruits. S4: In a dicotyledonous embryo, the scutellum is the single cotyledon found, whereas monocotyledonous embryos typically have two cotyledons. S5: Albuminous seeds, like pea and groundnut, have no residual endosperm as it is completely consumed during embryo development.
