To unravel a low fecundity in Zephyranthes candida (Lindl.) Herb., the development of the endosperm was studied using conventional paraplast section technique. The results show that the end...
Regular corn cells have nuclei with 20 chromosomes. Ten of these are derived from the egg cell and ten from the sperm nucleus that fertilizes the egg. Corn cross-pollinates when silks protruding from the ear shoot capture pollen grains from the tasse
