Document Summary
Chapter 7: the cell cycle and cell division. Cell division: a process by which a parent cell duplicates its genetic material and then divides into 2 similar cells. (linked to cell reproduction) Cells are basic compartments of life, where biological processes are separated from the external environment. A rapid and effective means of making new individuals, and it it common in nature. The offspring from asexual reproduction are clones, which are genetically identical. Mutations: genetic variations among parent and offspring. Multicellular eukaryotes (fungi and plants) can also reproduce asexually. The fusion of two specialized cells called gametes, and can result in offspring with considerable genetic variation. In many diploid organisms, the gametes form by meiosis (cell division). Resulting in the daughter cells with only half the genetic material of the original cell. Somatic cells: cells that are not specialized for reproduction. Homologous pairs: 2 sets of chromosomes in somatic cells (1 female 1 male)
