mitosis

reproductive process of cells, the cells nucleus divides so each new cell will have the same type and number of chromosomes as the parent cell

cytokinesis

splits the cytoplasm of a dividing cell into daughter cells

daughter cells

The cells that are produced as a result of mitosis. These cells are identical to each other, and also to the original parent cell.

spindle fibers

:fibers that attach to chromosomes and move the chromosomes by pulling homologous chromosomes in opposite directions and pushing the poles apart

cytoplasm

gel-like material inside the cell membrane of animals and plants; it is constantly moving, most of the cell;s life processes take place in the cytoplasm. .

interphase

cell growth phase where a cell increases in size, carries on metabolism, and duplicates chromosomes prior to division

telophase

last phase of mitosis, chromosome are in two new cells and nuclear membranes start to reform

anaphase

in this stage, the chormosomes are pullled away from thhe middle to the spindle poles of the cell

prophase

first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus

metaphase

second phase of mitosis, during which the chromosomes line up across the center of the cell

chromatid

one of the two strands of a chromosome that become visible during meiosis or mitosis

centromere

a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape

cell membrane

A structure that surrounds a cell, providng a barrier between the inside of a cell and the cells exterior enviornment

nucleus

has chromosomes that contain complex chemical information that directs all the celll;s activities, a membrane-enclosed command center in the cytoplasm of animal and plant cells

DNA

Deoxyribonucleic acid; the molecule that carries the hereditary information of the cell, it is the chemical blueprint for living things. It carries coded information that determines the features of an organism and ensures that these are copied and passed on to any offspring.

chromosomes

threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next
