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)

Indehiscent Fruits, the seeds remain in the fruit after the fruit is shed from the parents plant. * Most common is the achene

Simple fruit classification

Simple Fruits can be either dry or fleshy and result from the ripening of a simple or compound ovary with but one pistil.Simple fruits develop from a single ovary of a single flower and may be fleshy or dry. The simple fruits are divided into two type like: | | |  Fleshy Simple Fruits Simple Dry Fruits | | |

Fleshy Fruits| | |
Fleshy fruits types are the berry, in which the entire pericarp is soft and pulpy (e.g., the grape, tomato, banana, pepo, hesperidium, and blueberry) and the drupe, in which the outer layers may be pulpy, fibrous, or leathery and the endocarp hardens into a pit or stone enclosing one or more seeds (e.g., the peach, cherry, olive, coconut, and walnut). The name fruit is often applied loosely to all edible plant products and specifically to the fleshy fruits, some of which (e.g., eggplant, tomatoes, and squash) are commonly called vegetables. Dry Fruits| Dry fruits are divided into those whose hard or papery shells split open to release the mature seed (dehiscent fruits) and those that do not split (indehiscent fruits). Among the dehiscent fruits are the legume (e.g., the pod of the pea and bean), which splits at both edges, and the follicle, which splits on only one side (e.g., milkweed and larkspur); others include the dry fruits of the poppy, snapdragon, lily, and mustard....
