Document Summary
Apoptosis = form of cell death that is normal part of cell growth and development. Necrosis = cell death due to disease or injury. Cytokinesis = division of the cytoplasm and its contents. Centromeres = where spindle fibres attach (constriction of the chromosome) Amniocentesis = examines cells in fetal tissue by extracting amniotic fluid. Chronic villi sampling = cells of the chorion. Diploid = two sets of each chromosome 2n. Haploid gametes one set of each chromosome n. Zygote = prenatal human from the fertalized ovum stage until formation of embryo. Meiosis = cell division that halves the number of chromosomes to form haploid gametes. Haploid = cell with one set of chromosomes. Development = process of forming adult from single celled zygote. Evolution = genetic change in population over time. Blastocyst = hollow ball of cells descended from a fertalized ovum. Dizygotic = twins that originated as two fertalized ovum (fraternal twins)
