CELL DIVISION AND REPRODUCTION

Terms in this set (15)

anaphase
the stage of mitosis in which the chromosomes move to opposite ends of the cell
cell plate
a structure that forms across the middle of a higher plant cell in telophase; the beginning of a new cell wall which divides the two daughter cells from one another to finish mitosis
centriole
forms the ends of the spindle fibers in the cell during mitosis; normally found in animal cells
centromere
part of a chromosome that attaches to the spindle apparatus during mitosis or meiosis
chromatin
material in the cell nucleus that carries hereditary information; made up of DNA and various kinds of protein
cleavage furrow
a structure that forms around animal cells in telophase; a constriction in the middle of the parent cell that remains until the two halves of the cell divide into two, new daughter cells to finish mitosis
daughter cell
the cell produced as a result of cell division
interphase
period between two periods of mitosis
metaphase
the phase of mitosis in which the daughter chromosomes line up across the middle of the cell
mitosis
the process involving the division of the nucleus of a body cell
parent cell
the cell that begins the process of cell division
prophase
the first part of mitosis in which the chromosomes shorten and thicken, the nucleolus breaks down, and the nuclear envelope disintegrates
sister chromatids
two rod-like strands replicated by a chromosome during interphase; becomes a daughter chromosome by the end of cell division
spindle apparatus
a system of fibers stretching from one end of a mitotic cell to the other
telophase
the phase of mitosis in which the daughter chromosomes have reached opposite ends of the cell, the nuclear envelope and nucleolus reform, and the process of cytokinesis begins
