a one-celled microorganism that contains no nucleus

cell cycle

the sequence of growth and division that dividing cells go through

cell plate

structure formed in cytokinesis that divides the cytoplasm of a plant cell in half


cylindrical strutures in animal cells from which the spindle extends from in mitosis

eukaryotic cell

cell that has a true nucleus surrounded by a membrane


segments of DNA that carry information and give directions for everthing the cell is and will be

the second stage in mitosis in which the doubled chromosomes line up along the cell's equator and are split into single chromosomes


fiber-like structures that extend from opposite sides of the cell in mitosis; form the spindle


the separation of doubled chromosomes and the division of the nucleus into two nuclei that is necessary for cell division to occur in eukaryotic cells

nuclear envelope

a membrane that surrounds the nucleus in a eukaryotic cell


plural form of nucleus
