3 ) Ammonia molecule has an electronegative nitrogen atom bonded to three hydrogen atoms. Differences in electronegativity between nitrogen and hydrogen makes each hydrogen atom acquires positive charge. Thus, in the molecule, there is one negative site and three positive..

On reaching the stigma, the pollen grains put out a tube. This is called germination of the pollen grain. Fertilisation in a Flowering Plant The tip of the tube contains the male nuclei. The tube grows and enters the ovule where it bursts at the tip releasing the male gametes. One of..

As a result of copulation, semen containing sperms is ejaculated into the vagina. Once the semen (mixture of spermatozoa and accessory fluids) is deposited into the vaginal passage of the female, the spermatozoa start their journey through the uterus to reach the oviducts. On an average, the sperma..

After fertilization, the zygote undergoes a number of mitotic divisions and form a multicellular embryo. The primary endosperm nucleus also passes through a series of mitotic divisions and form a mass of endosperm cells which provide nourishment to the developing embryo. Based on the kind of develo..

As a result of fertilisation, the following changes are observed in a flower: 1. A diploid zygote is formed and develops into an embryo which is the future plant. 2. The triploid endosperm tissue serves as a source of nutrition for the developing embryo. 3. The ovule becomes s..
