Fruit Structure-

Some fruits consist of only the ovary and its seeds.Exocarp or Epicarp: This is the outermost layer of the pericarp that forms the skin. Mesocarp: It is the thick, fleshy and juicy middle layer of the pericarp. Endocarp: It is the innermost layer of the fruit which often develops into the pith.

Types of Fruits & Classification of fruits-

Types of Fruits 

•FLESHY FRUITS-Fruits whose mesocarp is at least partly fleshy at maturity are classified as fleshy fruits.

DRUPE-

BERRIES-

POMES-

•DRY FRUITS – Fruits whose mesocarp is definitely dry at maturity are classified as dry fruits. 

FOLLIDE-splits along one side or seam (suture) only. Examples include larkspur, columbine, milkweed, and peony.

LEGUME-splits along two sides or seams.Thousands of members of the Legume Family (Fabaceae) produce this type of fruit. Examples include peas, beans, garbanzo beans, lentils, carob, kudr mesquite.

SILIQUES-split along two sides of seams, but the seeds are borne on a central partition, which is exposed when the two halves of the fruit separate. Example broccoli, cabbage, radish, shepherd’s pune and watercress.

CAPSULE-the most common of the dry fruits that .They consist of at long the parutiound split a variety of ways. Some split along the partitions between the carpels, while others split through the cavities (locules) in the carpels. Still others form a cap toward one end. Example: Cotton.

Classification of fruits 

SIMPLE FRUITS-These fruits develop from a single ovary of one or more carpels.

AGGREGATE FRUITS-Derived from a single flower with several to many pistils.

MULTIPLE FRUITS-Derived from several to many individual

Fruit Development

Fruit development can generally be considered to occur in four phases:

Fruit set phase-the transition from flower to young fruit, a key step in the development of sexually reproducing higher plants. Plant hormones have important roles during flower pollination and fertilization, leading to fruit set.

Rapid cell division-follows immediately after fertilization, leading to a progressive increase in pericarp cell number. The end of this stage is marked by a sharp fall in the rate of cell division, which occurs after 2 weeks of pollination

Cell enlargement-during this phase, fruit growth continues, mostly as a result of cell enlargement, until the fruit reaches its final size.

Maturation and ripening- Maturation is related to changes in seed development, soluble solids and the cessation of fruit growth.Ripening based on the individual components of softening, starch breakdown and volatile production, and their control, are described.

Fruit Dispersal Mechanism

Dispersal may occur by a number of different means, including gravity (basically, a simple means of dispersal involving the seed falling and potentially rolling downslope a short distance), wind, water, animals, and human.

 Dispersal by wind- 

Definition: Seeds are carried away by the wind

Examples: Dandelion seeds-These seeds have fluffy, parachute-like structures called pappus that help them float on the wind.

Dispersal by animals-

Definition: Seeds are consumed by animals, and their undigested seeds are deposited in a new location through their droppings.

Examples: Berry-eating birds- Birds often consume berries and then excrete the seeds in their droppings, which can be deposited in a variety of habitats.

Dispersal by water-

Definition: Seeds are carried away by water currents.

Examples: Coconut seeds-Coconut seeds have a fibrous husk that keeps them afloat and protects them from saltwater. This allows them to be carried by ocean currents to distant shores.

Dispersal by human-Humans, both intentionally and unintentionally, are by far the most efficient transporters of fruits and seeds. Travelers and explorers have carried many noxious weeds and plant diseases, as well as valuable food and medicinal plants, from one continent to another.

Dispersal by Mechanical –

EXPLOSIVE MECHANISMS: Some plants, like witch hazel and dwarf mistletoe, have fruits that forcefully eject seeds.

GEYSER-LIKE ERUPTION: In plants like manroots and certain cucurbits, seeds are released in a frothy substance.

COILING TAILS:Filarees and other geraniums have fruits with coiling tails that “drill” seeds into the ground.

Nutritional And Economic Importance

Nutritional Importance-Fruits are essential components of a balanced diet, offering a plethora of vitamins, minerals, and antioxidants. They are low in calories but rich in fiber, which aids digestion and promotes satiety.

Economic Importance- Fruits play a significant role in the global economy, contributing to both agricultural production and trade.

6.Cultural Significance - Fruits have deep cultural significance in various societies around the world. They are often associated with celebrations, rituals, and traditional practices.

SYMBOLISM-SYMBOLISM-Fruits can symbolize fertility, abundance, and prosperity in different cultures.

RELIGIOUS SIGNIFICANCE-Fruits are often mentioned in religious texts and are used in religious ceremonies.

CUISINE-Fruits are integral to many cuisines, used in desserts, salads, and main dishes.
