How does the process of fertilisation take place in flowers?
Advertisements
उत्तर
- When pollen lands on the stigma, it germinates and gives rise to a pollen tube that passes through the style and reaches the ovary of a pistil.
- When the pollen tube reaches an ovule, it releases the male gametes. A male gamete fuses with a female gamete in the ovule.
- This process is known as fertilisation. The cell which is formed after the fusion of a male and a female gamete is known as zygote.
- This zygote divides several times in order to form the embryo present inside the seed.
