It is the mature ovary of a single orange blossom. Though it seems to have sections when cut open, all of these sections together come from a single ovary that develops into different layers. [7] Fruits are important in the dispersal and protection of seeds, and variation in fruit shape or size results from an evolutionary response that aids in ...
The female gametophyte — specifically termed a megagametophyte — is also called the embryo sac in angiosperms. The megagametophyte produces an egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule.
A pistil typically consists of an expanded basal portion called an ovary, an elongated section called a style and an apical structure called a stigma that receives pollen. The ovary (from Latin ovum, meaning egg) is the enlarged basal portion which contains placentas, ridges of tissue bearing one or more ovules (integumented megasporangia). The ...
A fleshy fruit was called a pericarpium. For Caesalpinus, a true bacca or berry was a pericarpium derived from a flower with a superior ovary; one derived from a flower with an inferior ovary was called a pomum. [24] In 1751, Carl Linnaeus wrote Philosophia Botanica, considered to be the first textbook of descriptive systematic botany. [25]
These fruits depend on animals to eat the fruits and disperse the seeds in order for their populations to survive. [3] Dry fruits also develop from the ovary, but unlike the fleshy fruits they do not depend on the mesocarp but the endocarp for seed dispersal. [3] Dry fruits depend more on physical forces, like wind and water.
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.
The resulting zygote develops into an embryo inside the ovule. The ovule, in turn, develops into a seed and in many cases, the plant ovary develops into a fruit to facilitate the dispersal of the seeds. Upon germination, the embryo grows into a seedling.

Its base is a so-called gynophore of 0.5 mm (0.020 in) long, followed by an ovary of 2.5 mm (0.098 in) with a papillose surface, next a glabrous style of 0.5 mm (0.020 in) thick at the point where it curves upwards for about 1.5 mm (0.059 in) and somewhat backwards. The ovary develops into a 1-seeded, hairless, papery thin fruit of 4 mm (0.16 ...
