Fruit formation begins with the pollination of a flower. Pollen from the male reproductive organs of a flower is transferred to the female reproductive organs, either by wind, insects, or other means. Once the pollen reaches the stigma of the flower, it travels down the style to the ovary.
Inside the ovary, the pollen fertilizes the ovules, which are the female reproductive cells. This fertilization triggers a series of biochemical reactions that lead to the development of the ovary into a fruit. The ovary wall thickens and the ovules develop into seeds.
As the fruit grows, it may undergo changes in color, size, and texture. The ovary wall may also develop into different layers, such as the exocarp (outer skin), mesocarp (fleshy middle layer), and endocarp (innermost layer surrounding the seeds). These layers can vary depending on the type of fruit.
Once the fruit is fully developed, it is ready for dispersal. This can occur through various means, such as animals eating the fruit and dispersing the seeds through their droppings, or the fruit falling to the ground and decomposing to release the seeds.
Overall, fruit formation is a complex process that involves pollination, fertilization, and the development of the ovary into a mature fruit containing seeds.

Fruit Formation
1. Pollination:
- Pollen grains from the anthers (male reproductive organs) are transferred to the stigma (female reproductive organ) of a compatible flower.
2. Fertilization:
- A pollen tube grows from the stigma, delivering sperm cells to the ovules (female gametes) in the ovary.
- Fertilization occurs when a sperm cell fuses with an egg cell within an ovule.
3. Ovule Development:
- The fertilized ovules develop into seeds, consisting of an embryo (future plant), endosperm (food reserve), and seed coat.
4. Ovary Transformation:
- The ovary, which originally housed the ovules, transforms into a fleshy or dry fruit.
5. Fruit Development:
- The ovary walls thicken and develop into the fruit wall or pericarp, consisting of three layers: exocarp (outer skin), mesocarp (flesh), and endocarp (inner lining).
- The developing fruit absorbs nutrients and water from the plant, increasing in size and weight.
6. Seed Maturation:
- Within the fruit, the seeds continue to mature, developing a hard seed coat and accumulating stored nutrients.
7. Ripening:
- As the fruit matures, it undergoes ripening, which involves changes in color, texture, flavor, and aroma.
- These changes are triggered by ethylene and other plant hormones.
8. Fruit Dispersal:
- Once ripe, fruits play a crucial role in plant reproduction by dispersing seeds.
- Dispersal mechanisms vary, including wind, animals, water, and gravity.
Types of Fruit Structures:
- Simple Fruits: Develop from a single ovary of a single flower, e.g., apple, banana, cherry.
- Aggregate Fruits: Develop from multiple ovaries of a single flower, e.g., strawberry, raspberry, blackberry.
- Multiple Fruits: Develop from multiple flowers that fuse together, e.g., pineapple, fig, mulberry.
