deficit in language comprehension or production due to brain damage, usually on the left hemisphere (similar deficit not usually found with damage to the right hemisphere)
The only exception is sperm or eggs which are produced by a different type of cell division called ________. meiosis. fertilization. sperm and egg unite to form a single cell called the zygote which contains chromosomes from the sperm and egg. The zygote undergoes mitosis to begin the development of the embryo which eventually becomes a baby
106 â A CHAPTER 4 Cell Reproduction Sexual Reproduction Another way that a new organism can be produced is by sex-ual reproduction. During sexual reproduction, two sex cells,sometimes called an egg and a sperm, come together. Sex cells,like those in Figure 9, are formed from cells in reproductiveorgans.Sperm are formed in the male reproductive organs. Eggs are formed in the female reproductive organs.The joiningof an egg and a sperm is called fertilization, and the cell thatforms is called a zygote (ZI goht).Generally, the egg and thesperm come from two different organisms of the same species.Following fertilization, mitosis and cell division begins.he joiningof an egg and a sperm is called fertilization, and the cell thatforms is called a zygote (ZI goht).
