Define cell increase.
Cell division increases the number of cells in the body.
Define cell decrease.
Cells reduced by apoptosis when necessary.
during late interphase chromatin is condensing into chromosomes and centrosomes have duplicated in preparation fo mitosis.
define:early prophase
during early prophase duplicated chromosomes are visible. Centrosomes begin moving apart;nuclear envelope is fragmenting, and nucleolus will disappear.
define:late prophase
spindle is in process of forming and centromeres of chromosomes are attaching to centromeric spindle fibers
Chromosomes (each consisting of two sister chromatids) are at the metaphase plate(center of fully formed spindle).
Daughter chromosomes (each consisting of one chromatid) are moving toward the poles of the spindle.
Daughter cells are forming as the nuclear envelopes and nucleoli appear. Chromosomes will become indistinct chromatin.
define the cell cycle.
repeating sequence of events in eukaryotic cells consisting of the phases of interphase, when growth and dna synthesis occurs, and the stages of mitosis when cell division occurs.
constricted region of a chromosome where sister chromatids are attached to one another and where the chromosome attaches to a spindle fiber.
Threadlike network in the nucleus that is made up of DNA and proteins.
Rodlike structure in the nucleus seen during cell division; contains the genes.
crossing over?
Exchange of corresponding segments of genetic material between nonsister chromatids of homologous chromosomes during synapsis of meiosis.
Protein that cycles in quantity as the cell cycle progresses;combines with and activates the kinases that function to promote the events of the cycle.
Division of the cytoplasm of a cell during telophase of mitosis or meiosis 1 and 2.
2n number of chromosomes, thice the number of chromosomes found in gametes.
Haploid reproductive cell. Two gametes, most often an egg or sperm, join in fertilation to form a zygote.
Diploid cell formed by the union of two gametes, the product of fertilization.
homologous chromosome?
Similarly constructed chromosomes with the same shape and that contain genes for the same traits, also called homologues.
Type of cell division that in animals occurs during the production of gametes and results in four daughter cells with the haploid number of chromosomes.
Type of cell division in which the daughter cells receive the exact chromosome and genetic makeup of the parent cell;occurs during growth and repairl
Production of an egg in females by the process of meiosis and maturation.
Polar body?
Non functioning daughter cell, formed during oogenesis, that has little cytoplasm.
Somatic cell?
In animals, a body cell, excluding those that undergo meiosis and become a sperm or egg.
Production of sperm in males by the process of meiosis and maturation.
