Caption: Lily embryo sac. Light micrograph of an embryo sac from the female reproductive parts of a lily flower (Lilium sp.). The embryo sac is inside an ovule (cells at bottom and left) that is itself inside an ovary. At centre is the megaspore mother cell, or megasporocyte (green, oval). Its nucleus (round, white) containing chromosomes (brown) is also seen. At this stage there are 2 of each chromosome, that is: the cell is diploid. The mother cell will undergo meiosis to produce 4 haploid (1 of each chromosome) megaspores, which will develop into gametophytes (sex cell producing cells). The mother cell is surrounded by a protective layer of integument. Magnification: x200 when printed at 10 centimetres tall.
