In the two images on the left (A and B), it is shown a gynoecium composed of two carpels with a leaf-like structure made up of epidermis enclosing parenchymatic tissue. The edges of carpel fuse to form the placenta, where ovules are inserted. Female gametophyte are formed in the ovules. C) In the ovules, the macrospore develops in the female gametophyte or embryonary sac, which contains 8 nuclei. In this image the female gametophyte is not yet fully developed. There is a parenchymatic tissue organized in two protective integuments, the outer integument or primine and the outer integument or secundine. Below the integuments, the nucellus is found wrapping the embryonary sac. In the embryonary sac, several types of cells can be distinguished. The sinergids are found close to the egg cell, the antipods are in the opposite site to the egg cell, and the central cell is in between. The funiculus is connecting the seed and the placenta. Micropyle is the structure that will allow to the microscopore contact with the egg cell.
