Representing a greatly enlarged idealized complete flower, this model teaches angiosperm pollination and fertilization. Three petals, three sepals and five stamen are detachable the ovary is dissected to reveal the 7-celled female gametophyte. Depicting the condition just prior to double fertilization, one sperm is destined to fertilize the two polar nuclei forming the nutritive triploid endosperm. The other will fertilize the eggs to form the diploid zygote. Numbered with English key card.
