Question

Draw a neat diagram showing fertilisation in a flower and label (a) Pollen
tube, (b) Male germ cell and (c) Female germ cell, on it. Explain the
process of fertilisation in a flower. What happens to the (i) ovary and
(ii) ovule after fertilisation ?​

Answer 1

PROCESS OF FERTILIZATION

Fertilization in flowering plants happens through a process called pollination. ... Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed. • Each seed contains a tiny, undeveloped plant called an embryo.

★ PROCESS OF FERTILIZATION IN OVARY

Ovary, in botany, enlarged basal portion of the pistil, the female organ of a flower. The ovary contains ovules, which develop into seeds upon fertilization. The ovary itself will mature into a fruit, either dry or fleshy, enclosing the seeds. ... The fertilized ovule develops into a seed

★ PROCESS OF FERTILIZATION OF OVOULE AFTER FERTILIZATION.

Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one...

Answer 2

Answer:

Fertilisation occurs after pollen grains fall on the stigma. Upon falling on the stigma, the pollen grains burst and grow a pollen tube taht passes downwards from the style to the ovary containing the ovule. The male gamete present in the pollen moves downward through the pollen tube and reaches the ovule.
