9 Meiosis CHAPTER OUTLINe Meiosis (p. 172) 9.1 Discovery of Meiosis (p. 172; Figs. 9.1‚ 9.2) A. In 1882‚ Belgian cytologist Pierre-Joseph van Beneden discovered that the gametes of the roundworm Ascaris contained two chromosomes while somatic cells contained four. B. Fertilization 1. van Beneden proposed in 1887 that an egg and sperm could fuse to form a zygote. 2. The fusion of gametes is called fertilization or syngamy. C. Meiosis 1. A reduction division is required to reduce the number

Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one
