Cytokinesis - division of a cell’s cytoplasm and organelles into two identical cellsCleavage furrow - a slight indentation of the plasma membrane, and is completed after telophase. The cleavage furrow usually appears midway between the centrosomes and ex- tends around the periphery of the cell.Reproductive cell divisionMeiosis - the reproductive cell division that occurs in the gonads. Produces gametes in which the number of chromosomes is reduced by half.Haploid cell (n) - gametes contain a single set of 23 chromosomes.
Meiosis I - which begins once chromosomal replication is complete, consists of four phases: prophase I, metaphase I, Meiosis II - The second stage of meiosis, meiosis II, also consists of four phases: prophase II, metaphase II, anaphase II, Describe how cells differ in size and shape, and homeostatic imbalances.Cellular diversity - The body of an average human adult is composed of nearly 100 trillion cells. All of these cells can be classified into about 200 different cell types. Cells vary considerably in size. The largest cell, a single oocyte, has a diameter of about 140 µm and is barely visible to the unaided eye. A red blood cell has a diameter of 8 µm.disorderscancer—general informationComplete the “Chapter Review and Resource Summary” at the end of the chapter.Work through the “Critical Thinking Questions” for this chapter in WileyPLUS and ORION.
