The Different Classes of Fruits

The Different Classes of Fruits

The fruit is a mature ovary which may or may not retain addition floral parts. A fruit in which such additional parts are retained is known as an accessory fruit.

Fruits are classified as

  • Simple
  • Multiple
  • Aggregate

The difference is according to the arrangement of the carpels from which the fruit is derived.

Aggregate Fruits

  • Consist of a number of separate carpels of one gynoecium

Aggregate Fruits Examples

  • Magnolia (Magnolia wilsonii)
  • Raspberry (Rubus idaeus)
  • Strawberry (Fragaria indica)

Dry simple fruits are classified as dehiscent or indehiscent

Dehiscent fruits, the tissues of the mature ovary wall beak open, freeing the seeds.

  • The follicle is derived from a single carpel
  • The pea (Poa) family is an example

Indehiscent Fruits, the seeds remain in the fruit after the fruit is shed from the parents plant.

  • Most common is the achene
  • Small single seeded fruit which likes free in the cavity, very loosely attached

Fantastic blog! Do you have any tips and hints for aspiring wreitrs? I'm hoping to start my own site soon but I'm a little lost on everything. Would you suggest starting with a free platform like WordPress or go for a paid option? There are so many options out there that I'm completely confused .. Any ideas? Thanks a lot!
