A milkweed follicle releasing its seeds.. In botany, a follicle is a dry unilocular fruit formed from one carpel, containing two or more seeds. [1] It is usually defined as dehiscing by a suture in order to release seeds, [2] for example in Consolida (some of the larkspurs), peony and milkweed (Asclepias).
An example of multiple fruits are the fig, mulberry, and the pineapple. [1] Simple fruits are formed from a single ovary and may contain one or many seeds. They can be either fleshy or dry. In fleshy fruit, during development, the pericarp and other accessory structures become the fleshy portion of the fruit. [2]
Dehiscent fruits that are derived from one carpel are follicles or legumes, and those derived from multiple carpels are capsules or siliques. [3] One example of a dehiscent fruit is the silique. This fruit develops from a gynoecium composed of two fused carpels, [3] which, upon fertilization, grow to become a silique that contains the ...
They can be follicles, capsules, nuts, achenes, drupes , and accessory fruits, like the pome of an apple, the hip of a rose, or the receptacle-derived aggregate accessory fruit of a strawberry. Many fruits of the family are edible, but their seeds often contain amygdalin, which can release cyanide during digestion if the seed is damaged. [18]
Fruits are the mature ovary of seed-bearing plants, and they include the contents of the ovary, which can be floral parts like the receptacle, involucre, calyx, and others that are fused to it. Fruits are often used to identify plant taxa, help to place the species in the correct family, or differentiate different groups within the same family.
In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels.
A raspberry fruit (shown with a raspberry beetle larva) is an aggregate fruit, an aggregate of drupelets The fruit of an Aquilegia flower is one fruit that forms from several ovaries of one flower, and it is an aggregate of follicles. However, because the follicles are not fused to one another, it is not considered an aggregate fruit
Cypsela – an achene-like fruit derived from the individual florets in a capitulum: . Fibrous drupe – (coconut, walnut: botanically, neither is a true nut.). Follicle – follicles are formed from a single carpel, and opens by one suture: ; also commonly seen in aggregate fruits: (magnolia, peony).
