In botany, dry fruits are fruits which have a hard, dry pericarp around their seeds, these commonly disperse via wind with help of 'wings' and 'parachutes' or via animals with help of hooks which latch on animal fur or when seeds are consumed by the animals. They are different from fleshy fruits based on their dry pericarp, [1] in which the exocarp, mesocarp and endocarp aren't clearly distinguishable from each other.
In common language, dry fruits may also refer to dried fruits and nuts. [2]
Dry fruits can be classed into dehiscent, indehiscent and schizocarpic dry fruits. [1]
In dehiscent dry fruits, the pericarp splits open to release the seeds, these include capsules, follicles and legumes. While in indehiscent dry fruits, the pericarp doesn't split open and seeds generally dispersed by wind or animals, these include nuts, achenes, caryopses, samaras and nutlets. In schizocarps, the fruit splits open but the seeds are not released, these include cremocarps and double samaras. [1]
Dehiscent dry fruits like legumes, including peas, generally have a thin pericarp around all the seeds, which are attached to the placenta by a funicle, these split open after they're matured and the seeds are scattered. Capsules, like love-in-a-mist, develop from fused carpels. Follicles, like larkspur, develop from a single carpel and have two seeds. [1]
Indehiscent dry fruits like nuts, including chestnuts, have a husk or shell formed from bracts which doesn't split open to release the seeds. Although strawberries are accessory fruits, they are covered in small achenes, which are single-seeded dry fruits. [1]
Schizocarps like cremocarps, which includes hogweed, have a flattened pericarp and both carpels of the fruit separate into mericarps (half-fruits) without exposing the seeds. Double samaras, like maples, have two mericarps, each having a wing and a seed. [1]
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering.
In botany, a drupe is a type of fruit in which an outer fleshy part surrounds a single shell of hardened endocarp with a seed (kernel) inside. Drupes do not split open to release the seed, i.e., they are indehiscent. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries.
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, many dry seeds are called nuts. In a botanical context, "nut" implies that the shell does not open to release the seed (indehiscent).
In botany, a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms.
An achene, also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate and indehiscent. Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat.
In botany, a caryopsis (pl. caryopses) is a type of simple fruit—one that is monocarpellate and indehiscent and resembles an achene, except that in a caryopsis the pericarp is fused with the thin seed coat.
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part. Structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay or predation to release the contents.
An aggregate fruit or etaerio is a fruit that develops from the merger of several ovaries that were separated in a single flower. In contrast, a simple fruit develops from one ovary, and a multiple fruit develops from multiple flowers. In languages other than English, the meanings of "aggregate" and "multiple" fruit are reversed, so that "aggregate" fruits merge several flowers. The differences in meaning are due to a reversal in the terminology by John Lindley, which has been followed by most English-language authors.
A silique or siliqua is a type of fruit having two fused carpels with the length being more than three times the width. When the length is less than three times the width of the dried fruit it is referred to as a silicle. The outer walls of the ovary usually separate when ripe, then being named dehiscent, and leaving a persistent partition. Siliques are present in many members of the mustard family, Brassicaceae, but some species have silicles instead. Some species closely related to plants with true siliques have fruits with a similar structure that do not open when ripe; these are usually called indehiscent siliques.
A schizocarp is a dry fruit that, when mature, splits up into mericarps.
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels, and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries.
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines), persimmons and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower. The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as Capsicum species, with air rather than pulp around their seeds.
Spirostachys africana is a medium-sized deciduous tree with a straight, clear trunk, occurring in the warmer parts of Southern Africa. Its wood is known as tamboti, tambotie, tambootie or tambuti.
In botany, a follicle is a dry unilocular fruit formed from one carpel, containing two or more seeds. It is usually defined as dehiscing by a suture in order to release seeds, for example in Consolida, peony and milkweed (Asclepias).
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.
Fruits are the mature ovary or ovaries of one or more flowers. They are found in three main anatomical categories: aggregate fruits, multiple fruits, and simple fruits.
This glossary of botanical terms is a list of definitions of terms and concepts relevant to botany and plants in general. Terms of plant morphology are included here as well as at the more specific Glossary of plant morphology and Glossary of leaf morphology. For other related terms, see Glossary of phytopathology, Glossary of lichen terms, and List of Latin and Greek words commonly used in systematic names.
Simple fruits are the result of the ripening-to-fruit of a simple or compound ovary in a single flower with a single pistil. In contrast, a single flower with numerous pistils typically produces an aggregate fruit; and the merging of several flowers, or a 'multiple' of flowers, results in a 'multiple' fruit. A simple fruit is further classified as either dry or fleshy.
