Fertilization, fruit, and seed formation are essential processes in the life cycle of flowering plants.
Fertilization occurs when pollen from the male reproductive organ of a flower, the stamen, lands on the female reproductive organ, the pistil. The pollen grain then germinates and grows a pollen tube that penetrates the ovule, which contains the egg cell. The sperm cell from the pollen grain then fertilizes the egg cell, forming a zygote. This process results in the formation of a seed.
After fertilization, the ovule develops into a seed, which contains the embryo of the plant. The ovary of the flower also begins to develop into a fruit, which surrounds and protects the developing seeds. The fruit provides nutrients and protection for the seeds as they mature.
As the seeds mature, the fruit ripens and eventually falls from the plant, allowing the seeds to be dispersed. This dispersal can occur through various means, such as wind, water, animals, or gravity. Once the seeds are dispersed, they can germinate and grow into new plants, completing the life cycle of the flowering plant.
Overall, fertilization, fruit, and seed formation are crucial processes in the reproduction and propagation of flowering plants. These processes ensure the survival and continuation of plant species in their environment.

Fertilization
Fertilization is the process by which a female gamete (ovule) is combined with a male gamete (pollen) to form a zygote.
1. Pollination: Pollen grains from the male anther are transferred to the female stigma.
2. Pollen tube formation: A pollen grain germinates on the stigma, forming a pollen tube that grows down the style towards the ovary.
3. Discharge of sperm: The pollen tube carries two sperm cells to the ovary.
4. Double fertilization: One sperm cell fuses with the egg cell (central cell) to form the zygote, while the other sperm cell fuses with two polar nuclei to form the endosperm, which provides nutrients for the developing embryo.
Fruit Formation
The ovary of the flower develops into a fruit after fertilization. The fruit protects the developing seeds.
1. Ovule development: After fertilization, the zygote develops into an embryo, and the ovule develops into a seed.
2. Ovary wall development: The ovary wall thickens and becomes a fruit, which can be fleshy (e.g., apple, tomato) or dry (e.g., pea pod, bean pod).
3. Fruit dispersal: Fruits are adapted for dispersal by various means, such as wind, animals, or water.
Seed Formation
Seeds contain the embryo and provide nutrients for its growth.
1. Embryo development: The zygote divides to form an embryo, consisting of a root, shoot, and one or two cotyledons (seed leaves).
2. Seed coat formation: The ovule integuments thicken and form a protective seed coat.
3. Seed maturation: The embryo and seed coat mature and dry out.
Importance of Fertilization, Fruit, and Seed Formation
- Reproduction: Fertilization produces a zygote, which develops into a new individual.
- Fruit protection: Fruits provide protection for the developing seeds.
- Seed dispersal: Seeds are adapted for dispersal, ensuring the survival of the plant species.
- Nutrition: Seeds contain nutrients for the growth of the new plant.
- Agriculture: Fertilization, fruit, and seed formation are essential processes in plant cultivation and agricultural practices.
