When a grain of pollen reaches the stigma, it creates a pollen tube for the sperm to journey down the style and fertilize the ovule; fertilized ovules become seeds. Fertilization is the death of the flower, as the petals drop or wither at this point and the ovary starts to enlarge and ripen into what we know as fruit.

What changes occur in the various parts of a flower?
(i) The petals, stamens, style and stigma of the flower fall off. (ii) Sepals dry up and hold the ovary. (iii) The ovules confined in the ovary develop into seeds. (iv) The ovary develops into fruit.
Which part of plant changes fruit?
The ovary of a flower becomes the fruit of the flower.
What happens to flower after fertilization?
After fertilization the flower withers. The sepals and the petals dry up, the ovary converts into fruit, the ovule forms the seed and the zygote forms the embryo which is enclosed in the seed.
What is the fate of flower after fertilization?
Solution: After the pollination, fertilization takes place in the flowers. It is then converted into the seeds which further develop into a fruit. When the pollen grain sticks to the stigma of the flower, it gets fertilized and further develops into a fruit of the plant.
Which is the most beautiful part of plant?
Flowers. Flowers are the most beautiful and colourful part of a plant. They are the reproductive part of a plant.
Which part of flower turns into seed?
Once pollen gets to the ovary within the flower, the ovary develops into a fruit. The ovules inside the ovary develop into seeds inside of this fruit.
What do fruits have inside them?
They are fruit because they all have blossoms which mature into plant parts with juicy flesh. Inside the juicy flesh are seeds. Fruits contain seeds. When a fruit falls to the ground, the flesh provides nourishment for the young seedling.
What are the 4 steps of fertilization?
The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
What are the 6 steps of fertilization?
What are the 6 steps of fertilization?
- Sperm Capacitation.
- Sperm-Zona Pellucida Binding.
- The Acrosome Reaction.
- Penetration of the Zona Pellucida.
- Sperm-Oocyte Binding.
- Egg Activation and the Cortical Reaction.
- The Zona Reaction.
- Post-fertilization Events.
Which part of the flower continue to develop after fertilization?
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 or more seeds.
What is the fate of part C after fertilization?
The calyx may either remain intact in a dried and shrivelled form or fall off. The ovary enlarges to form the fruit, the ovarian wall forms the fruit wall. The ovary wall may either form a fleshy fruit wall or form a dry and hard fruit wall. Ovules go on to become the seed.
What are the changes after fertilization?
= After fertilization, the following changes are observed in a flower: There is formation of a diploid zygote and it develops into an embryo, which forms the future plant. The endosperm cells serve as a source of nutrition for the developing embryo. The ovule becomes the seed.
What is a Hypogynous flower?
Hypogynous flowers: The flowers in which gynoecium occupies the highest position while the other parts are situated below it is called hypogynous flowers. The ovary in this variety is said to be superior, e.g., mustard, china rose, and brinjal.
