Class 12 Biology Reproduction Sexual reproduction in Flowering Plants



The structure which can show the effect of traits brought by the male gamete immediately after its formation is
(a)
Embryo
(b)
Cotyledons
(c)
Endosperm
(d)
Plumule
Correct answer: (c) 
Solution: 
Endosperm nourishes the developing embryo. It is formed by the fusion of male gamete with the diploid secondary nucleus that results in the formation of a triploid primary endosperm mother cell. In double fertilization, one male gamete fuses with the egg cell to form the zygote and the other male gamete fuses with the diploid secondary nucleus to form the endosperm. It is formed immediately after fertilization because it has to nourish the developing embryo. So, the correct answer is C.
