AN OVARY FROM FUSED LEAVES. “The female reproductive organ of flowering plants (angiosperms) is called the gynoecium and develops in the middle of the flower as congenitally fused carpels, which have evolved from leaves. After fertilisation, the gynoecium develops into a fruit that nurtures and protects the seeds inside until their dispersal at maturity.“ http://www.sciencedirect.com/science/article/pii/S0959437X16301903 View in LinkedIn

COMPLEX OVARY. “The gynoecium is a particularly complicated plant organ that is partitioned into a number of highly specialized tissues within which the female gametophytes (ovules) are produced.” http://www.sciencedirect.com/science/article/pii/S0959437X16301903 View in LinkedIn

CLASSIFICATION. “Angiosperms distinguish themselves from gymnosperms by their ovules that are enclosed before pollination.” https://lnkd.in/dmBiWHf View in LinkedIn

TRANSFORMATIVE STRUCTURE. “The carpel is the female reproductive organ, enclosing one or more ovules, of the angiosperm flower. Carpel origin and associated processes (carpel fusion, placenta formation etc) represent perhaps the most important events in the anatomical evolution of the angiosperms.” https://lnkd.in/d2EsAxW View in LinkedIn

THE PRECURSOR TO FRUIT. “The carpel is the female reproductive organ that encloses the ovules in flowering plants or angiosperms. The origin of the carpel and its subsequent morphological modifications were probably of vital importance to the evolution of the angiosperms, and the carpel is also very important as the precursor organ to the fruit.” https://lnkd.in/dN-h-K2 View in LinkedIn

“THE PISTILS OF A FLOWER are considered to be composed of carpels. A carpel is a theoretical construct interpreted as modified leaves bearing structures called ovules, inside which the egg cells ultimately form. A pistil may consist of one carpel, with its ovary, style and stigma, or several carpels may be joined together with a single ovary, the whole unit called a pistil.” https://en.m.wikipedia.org/wiki/Gynoecium View in LinkedIn

UNIQUE STRUCTURES. “The angiosperm carpel is one of the defining characteristics of flowering plants. Carpels are unique to angiosperms and are found in all of its members. Yet, due to the distinctive structure and function of carpels, deducing homologies among carpels and other seed-plant organs has been difficult.” https://lnkd.in/dEJykw4 View in LinkedIn

A BIG LEAP FORWARD. “The carpel, or female reproductive organ enclosing the ovules, is one of the major evolutionary innovations of the flowering plants.” https://lnkd.in/dbZEjuz View in LinkedIn

FIRST NEW GENES. “Gene duplications that took place in the pre-angiosperm lineage, before the evolution of the first flowering plants, provided novel gene clades of potential importance for the origin of the carpel.” https://lnkd.in/dbZEjuz View in LinkedIn
