The mature female gametophyte plant, consisting of seven cells produced by the megaspore. These cells include the egg and the central cell, which contains two nuclei.
In angiosperms, the female gametophyte. Found within the ovule, it consists of eight or fewer cells, membrane bounded, but without cellulose walls between them.
A large cell that develops in the ovule of flowering plants. It contains a large number of nuclei derived by division of the megaspore nucleus. At the micropyle end is the egg nucleus and two synergids; at the opposite end are nuclei that will become the antipodals and in the centre are two polar nuclei which fuse to become the primary endosperm nucleus.
The female gametophyte of angiosperms, formed from the growth and division of the megaspore into a multicellular structure with eight haploid nuclei.
Alternate term applied to the angiosperm female gametophyte contained within a megaspore. PICTURE
The tissue in a plant ovule that contains the egg, the antipodals, the polar nuclei and the synergids.
The female gametophyte of a flowering plant, inside the ovule.
An embryo sac is a large cell that develops in the ovule of flowering plants. It contains the egg cell which, when fertilized, becomes an embryo, and then, eventually, a seed.
