MITOSIS

CELL WALL

The relatively rigid boundary of cells of plants and certain organisms.


NUCLEUS

The organelle of a living cell that contains chromosomes and is essential to the regulation and control of all the cells functions.


NUCLEAR MEMBRANE

The double-layered membrane surrounding the nucleus of a eukaryotic cell, separating the nucleoplasm from the cytoplasm.


POLES

an invisible focal point toward each end of a cell from which spindle fibers extend in arcs during mitosis or meiosis.


EQUATOR

Formed by the cell plate during the tele phase stage of meiosis.


KINETOCHORE

A specialized protein complex that developes on the vertical face of a centromere during late prophase; spindle fibers are attached to it.


SPINDLE FIBERS

structures consisting of microtubules that assist in chromosome separation during cell division.


CENTROMERES

The dense, constricted portion of a chromosome to which spindle fibers is attached.


CHROMOSOMES

A body consisting of a linear sequence of genes and composed of DNA and proteins.


SISTER CHROMATID

Two identical strands joined by a common centromere as a result of a chromosome that duplicated during the S phase of the cell cycle.



Sister Chromatids are separated during mitosis so that the two daughter cells would have identical sets of chromosomes.

CELL PLATE

The precursor of the middle lamella, it forms the equator during telophase.


DAUGHTER CHROMOSOMES

Chromatid that becomes a chromosome after separation from duplicated DNA molecule.


DAUGHTER CELLS

Independent cell after completion of mitosis or meiosis.
