Fruit

Fruits are also found commonly in such manufactured foods as cookies, muffins, yoghurt, ice cream, cakes, and many more. In vehicles:. Many fruits, including fleshy fruits like apples and mangos, and nuts like walnut, are commercially valuable as human food, eaten both fresh and made into jams, marmalade and other preserves for future consumption. In hip hop:. This is an evolutionary mechanism to increase dispersal distance away from the parent. In food:. Other fruits are elongated and flattened out naturally and so become thin, like wings or helicopter blades. Grill or grills may refer to:.

Some fruits have coats covered with spikes or hooked burrs, either to prevent themselves from being eaten by animals or to stick to the hairs of animals, using them as dispersal agents. Grille (artillery), a tank used by Germany during World War II. Variations in fruit structures largely relate to dissemination (called dispersal) of the seeds they contain. Grille, an opening in the bodywork of a vehicle to allow air to enter. Seedlessness in table grapes results from the abortion of the embryonic plant that is produced by fertilization, a phenomenon known as stenospermocarpy which requires normal pollination and fertilization. Grills, removable cosmetic dental metal apparati. Most seedless citrus fruits require a pollination stimulus; bananas and pineapples do not. Grillz, a 2005 rap single by Nelly.

Parthenocarpic fruit set may or may not require pollination. Grilling, a form of cooking that involves direct heat. In some species, seedlessness is the result of parthenocarpy, where fruits set without fertilization. Grill (cooking), a device or surface used for cooking food, usually fueled by gas or charcoal. Some cultivars of citrus fruits (especially navel oranges and mandarin oranges), table grapes, grapefruit, and watermelons are valued for their seedlessness. Commercial cultivars of bananas and pineapples are seedless.

Seedlessness is an important feature of some fruits of commerce. After fertilization, each flower develops into a drupe, and as the drupes expand, they connate (merge) into a multiple fleshy fruit called a syncarp. First an inflorescence of white flowers called a head is produced. In the photograph on the right, stages of flowering and fruit development in the noni or Indian mulberry (Morinda citrifolia) can be observed on a single branch.

Examples are the pineapple, edible fig, mulberry, osage-orange, and breadfruit. Each flower produces a fruit, but these mature into a single mass. A multiple fruit is one formed from a cluster of flowers (called an inflorescence).
.

In all these examples, the fruit develops from a single flower with numerous pistils. The strawberry is also an aggregate-accessory fruit, only one in which the seeds are contained in achenes. In some bramble fruits (such as blackberry) the receptacle is elongate and part of the ripe fruit, making the blackberry an aggregate-accessory fruit. An example is the raspberry, whose simple fruits are termed drupelets because each is like a small drupe attached to the receptacle.

An aggregate fruit, or etaerio, develops from a flower with numerous simple pistils. Types of fleshy, simple fruits (with examples) are:. Fruits in which part or all of the pericarp (fruit wall) is fleshy at maturity are simple fleshy fruits. Types of dry, simple fruits (with examples) are:.

Dry fruits may be either dehiscent (opening to discharge seeds), or indehiscent (not opening to discharge seeds). Simple fruits can be either dry or fleshy and result from the ripening of a simple or compound ovary with only one pistil. There are three basic types of fruits:. To these two basic definitions can be added the clarification that in botanical terminology, a nut is a type of fruit and not another term for seed.

Seeds are ripened ovules; fruits are the ripened ovularies or carpels that contain the seeds. It will also be seen that many common terms for seeds and fruit are incorrectly applied, a fact that complicates understanding of the terminology. Fruits are so varied in form and development, that it is difficult to devise a classification scheme that includes all known fruits. Since other parts of the flower may contribute to the structure of the fruit, it is important to study flower structure to understand how a particular fruit forms.

When such other floral parts are a significant part of the fruit, it is called an accessory fruit. In some fruits, especially simple fruits derived from an inferior ovary, other parts of the flower (such as the floral tube, including the petals, sepals, and stamens), fuse with the ovary and ripen with it. The pericarp is often differentiated into two or three distinct layers called the exocarp (outer layer - also called epicarp), mesocarp (middle layer), and endocarp (inner layer). The wall of the fruit, developed from the ovary wall of the flower, is called the pericarp.

With some multiseeded fruits the extent of development of the flesh of the fruit is proportional to the number of fertilized ovules. Fruit development continues until the seeds have matured. The ovary eventually comes to form, along with other parts of the flower in many cases, a structure surrounding the seed or seeds that is the fruit. The petals of the flower fall off and the ovule develops into a seed.

After an ovule is fertilized in a process known as pollination, the ovary begins to expand. In the commercial world, European Union rules define carrot as a fruit for the purposes of measuring the proportion of "fruit" contained in carrot jam. For example, rhubarb may be considered a fruit, though only the astringent stalk or petiole is edible. Rarely, culinary "fruits" are not fruits in the botanical sense.

These include cucurbits (e.g., squash and pumpkin), maize, tomato, cucumber, aubergine (eggplant), and sweet pepper, along with nuts, and some spices, such as allspice, nutmeg and chiles. Many foods are botanically fruits, but are treated as vegetables in cooking. . A plant that does not produce fruit is known as acarpous, meaning essentially "without fruit".

Such fruits are seedless. In a few species, the fruit may develop in the absence of pollination/fertilization, a process known as parthenocarpy. With most fruits pollination is a vital part of fruit culture, and the lack of knowledge of pollinators and pollenizers can contribute to poor crops or poor quality crops. Some gymnosperms, such as yew, have fleshy arils that resemble fruits and some junipers have berry-like, fleshy cones.

The term false fruit (pseudocarp, accessory fruit) is sometimes applied to a fruit like the fig (a multiple-accessory fruit; see below) or to a plant structure that resembles a fruit but is not derived from a flower or flowers. However, a great many common vegetables, as well as nuts and grains, are the fruit of the plant species they come from. In cuisine, when discussing fruit as food, the term usually refers to just those plant fruits that are sweet and fleshy, examples of which include plum, apple and orange. Botanical terminology for fruits is inexact and will remain so.

No one terminology really fits the enormous variety that is found among plant fruits. Evolution has led plants to adopt certain basic mechanisms, seemingly without close regard to the tissues involved. Fruits are the means by which flowering plants disseminate seeds. In many species, the fruit incorporates the ripened ovary and surrounding tissues.

In botany, a fruit is the ripened ovary—together with seeds—of a flowering plant.
