Ovule with Embryo Sac, SEM
Scanning electron micrograph of ovule with embryo sac. In seed plants, the ovule (small egg) is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the integument(s) forming its outer layer(s), the nucellus (or remnant of the megasporangium), and female gametophyte (formed from haploid megaspore) in its centre. After fertilization, the ovule develops into a seed. In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. Magnification is 40x at 12.7cm image size.
