The Biology Physiology and Sociology of Reproduction Kitap Açıklaması: “The most fundamental one of the activities for the maintenance of the race is reproduction. Ever y living organism, whether plant or animal, possesses the power to reproduce its kind. Some plants produce spores and some produce seeds. Reference was made above to the production of the flower in plants. The flower represents the reproductive organ of the plant, and the real object of the flower is to produce the seed. Animals produce eggs from which the young develop, either through a process of incubation outside of a maternal body or an analogous process within the maternal body. In the latter case the young are brought forth as living organisms.”(Tanıtım Bülteninden)
