embryo sac

This entire structure with its eight nuclei is called the embryo sac.

The large central cell of the embryo sac contains two polar nuclei.

In flowering plants, they are replaced by the embryo sac inside the ovule.

The female gamete is produced inside the embryo sac of the ovule.

The cell closest to the opening of the embryo sac becomes the egg cell.

In flowering plants, the female gametes are made of only eight cells, called the embryo sac, inside the ovule.

These develop into reduced megagametophytes (often called embryo sacs) within the ovule.

The megagametophyte (also called the embryo sac in flowering plants) produces the egg cell for fertilization.

Oogenesis occurs within the embryo sac and leads to the formation of a single egg cell per ovule.

Also, the most basal angiosperms still contain the four cell embryo sac and produce diploid endosperms.

During the development of the embryo sac inside a flowering plant ovule, the three cells at the chalazal end become the antipodal cells.

In Lilium which has a tetrasporic pattern, the central cell of the embryo sac is 4N.

In angiosperms, the megagametophyte is reduced to only a few nuclei and cells, and is sometimes called the embryo sac.

The megaspores become megagametophytes (embryo sacs).

In the flowering plants, the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.

In flowering plants, the megagametophyte (also referred to as the embryo sac) is much smaller and typically consists of only seven cells and eight nuclei.

In flowering plants, the female gametophyte has been reduced to an eight-celled embryo sac within the ovule inside the ovary of the flower.

The ovule contains a megagametophyte, also known as an embryo sac, that is bipolar in structure and contains 8 cell nuclei.

The bisporic and tetrasporic patterns undergo varying processes and result in varying embryo sacs as well.

In oaks, early fertilized ovules prevent the fertilization of other ovules by inhibiting the pollen tube entry into the embryo sac.

The female gametophyte, the megagametophyte, that participates in double fertilization in angiosperms is sometimes called the embryo sac.
