NEET BIOLOGY

Detailed explanation-1: -Fertilisation takes place inside the ovary when the nucleus of pollen grain fuses with the nucleus of an ovule to produce a zygote.

Detailed explanation-2: -Fertilization occurs as a sperm cell in a pollen tube fuses with the egg cell of an ovule, resulting in a plant embryo.

Detailed explanation-3: -Each ovule contains an egg. 1 Pollen grains land on the stigma and begin to grow pollen tubes. Sperm cells within the pollen grain move down the pollen tube and into an ovule. Fertilization occurs as one of the sperm cells fuses with the egg inside the ovule.

Detailed explanation-4: -During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary. Male reproductive cells travel down the tube and join with the ovule, fertilizing it. The fertilized ovule becomes the seed, and the ovary becomes the fruit.

Detailed explanation-5: -Fertilization: After the pollen grain lands on the stigma of the flower the process of fertilization takes place. The process in which the male gamete released from the pollen grains fuse with the female gamete present in the ovule is known as fertilization.
