Expert Member C Formation of fruits and seeds

The formation of fruits and seeds take place after a flower is successfully fertilized! There are 4 stages involved in the formation of fruits and seeds.

1. A flower is first fertilized to begin the first stage.
2. The petals and stamens will wither and fall off.
3. The ovary will then begin to grow and form into a fruit.
4. The fruit, the fertilized ovules start to form the seeds.
   
   
   
   

Pericarp is the part of the fruit which develops from the ovary wall. The inner layer of the pericarp, called the endocarp, develops from the inner epidermis of the ovary wall. The middle layer of the pericarp is called the mesocarp and develops from the middle layer of cells of the ovary wall. The outer layer of the pericarp is known as the exocarp and develops from the outer epidermis of the ovary wall.

Fruit development in Apple
This is an example of the formation of fruits in an apple flower. The petals have been lost and the stigmas are withering. The stamens will soon die as well.

The apple has an ovary which is below the attachment of the other floral parts.

The parts of the flower surrounding the ovary is called the floral tube and forms a large part of the mature fruit which develops out of it.
