We found that 12.5 % of peripheral cells yet only 0.6 % of central cells were BrdU - labeled in flank retinas (2,063 cells from ten flank retinas were counted, p < 0.001). (journals.plos.org)
Reproduction of flowering plants occurs within a plant's ovule by the fertilisation of both the egg and a larger central cell by two sperm cells. (sciencedaily.com)
Transmission electron microscopy of the unfertilized ovule revealed a very thin cell wall between the synergid cell and central cell wall, which was assumed to be necessary for rapid disintegration of the cell walls. (sciencedaily.com)
