    The peanut (Arachis hypogaea) is a dehiscent legume that is harvested from below the soil. The legume was originally formed above ground following pollination. After fertilization, the flower stalk of the peanut curves downward, and the developing pod is forced into the ground by the proliferation and elongation of cells under the ovary. The pod typically contains two seeds, each with a papery seed coat. Peanut seeds are eaten raw, salted and roasted. Peanuts are ground into peanut butter and Thai peanut sauce, and the expressed oil is used in cooking. Peanuts are also used in cookies, peanut brittle and candy bars. http://waynesword.palomar.edu/ecoph8b.htm Considering double fertilization in angiosperms, how many sperm are involved in the formation of a mature 2-seeded peanut pod?
