Fruits are produced only by flowering plants ( angiosperms ). Following pollination of the flower, the fertilize ovules develop into seeds while the surrounding ovary wall forms the fruit weave, or pericarp .

Types of Fruits

The botanic definition of a fruit is an organ that contains seeds, protecting these as they develop and frequently aiding in their dispersion. This may be at odds with casual use of the word “ fruit. ” Botanically, pineapples, oranges, and apples are fruits, but so excessively are “ vegetables ” like tomatoes and cucumbers. The pods that contain peas and beans are fruits, as are the dry, inedible structures that bear the seeds of many godforsaken plants .

A strawberry plant with blossoms and fruit. The true fruit of the strawberry is not the fleshy tissue but the tiny seedlike achenes on the surface of the berry.

MAJOR FRUIT TYPES

Type

Definition

Examples

SIMPLE
From a single pistil  

DRY INDEHISCENT
At maturity dry; does not split open  

Achene
Close-fitting pericarp surrounding a single seed Sunflower

Grain
Close-fitting pericap fused to a single seed Corn, wheat

Nut
Thick, woody pericarp surrounding a single seed Walnut, hazelnut

DRY DEHISCENT
At maturity dry and splits open  

Legume
Pod that splits along two opposite sides Beans, peas

Capsule
Fruit opening by several splits or pores Cotton, poppy

Schizocarp
Fruit splitting into 1-seeded segments Dill

FLESHY
Mostly fleshy at maturity; do not usually split open

Drupe
1- to 2-seeded; the innermost pericarp layer, stony and enclosing
the seed(s)
Plum, peach

Berry
1- to many-seeded; no stony innermost layer of pericarp Tomato, grape, (all citrus fruit are berries of a special type
termed a hesperidium)

AGGREGATE
Formed by fusion of several separate pistils of one flower Raspberry, cherimoya

MULTIPLE
Formed by fusion of several separate pistils of several grouped
flowers
Pineapple, fig

There are many ways to classify fruits, but the simplest differentiation is between fleshy and dry fruits. Fleshy fruits are made of living cells and are frequently fat and sweet ( oil-rich olives and avocados are exceptions ). dry fruits at maturity are made up of dead cells and are divided into those that split capable ( dehiscent fruit ) and those that do not ( indehiscent yield ). Within these broad categories many specialized yield types are recognized. Nuts ( for case, hazelnuts and pecans ) are one such class, defined as dry, indehiscent fruits with a hard, rocky wall. everyday custom of the bible “ addict ” is, however, quite different, and includes cashew nuts and peanuts ( which are actually seeds not fruits ).

truthful fruits are formed by the ovary, which is the lower region of the
pistil
and the female sex organ of the bloom. Sometimes the bulge of the fruit is not derived from the ovary but from some early part ( sulfur ) of the flower. such fruits are termed false fruits or accessory fruits. Strawberry is a good example of this. The fleshy weave people consider the yield is derived from the receptacle ( the swollen gratuity of the bloom stalk ), and the true fruits are the bantam, seedlike achenes on the surface .
apart from strawberry, all the fruit types discussed indeed far are bare fruits derived from single pistils. In contrast to simple fruits are sum and multiple fruits, which are formed from many pistils and, in go, manyExamples of the many classifications of fruits. The botanical definition of a fruit may be at odds with everyday usage of the word.
ovaries. Aggregate fruits like raspberries and blackberries are formed from the several ovaries of a single flower. multiple fruits like pineapples and mulberries develop from the fusion of the ovaries of several flowers. Interest-ingly, some fruits ( such as banana ) develop without seed constitution, a phenomenon termed parthenocarpy .
