Document Summary
Chapter 7: the cell cycle and cell division. Concept 7. 1 different life cycles use different modes of cell reproduction. Cell division: a process by which a parent cell duplicates its genetic material and then divides into two similar cells and sexual reproduction. Organisms have two basic strategies for reproducing themselves: asexual reproduction. Asexual reproduction by binary fission or mitosis results in genetic constancy. Asexual reproduction: rapid and effective means of making new individuals without the union of genetic material from two different parents; often takes place by budding or fragmentation and the offspring are genetically identical to their parent (clones) Any genetic variation among the parent and offspring comes from mutations. Single celled prokaryotes reproduce by binary fission, an asexual process. Single celled eukaryotes can reproduce asexually through mitosis followed by cytokinesis (many multi-celled eukaryotes can reproduce asexually as well) Sexual reproduction by meiosis results in genetic diversity.
