CELL CYCLE, CELL DIVISION worksheet

Your name: ________________________________

On each line, write the term that correctly replaces the underlined words in each sentence.

cell cycle

cytokinesis

mitosis

eukaryotic

binary fission

stem cell

centromere

daughter cells

prokaryotic

interphase

sister chromatids

______________________ At the end of the cell cycle, the division of the cell’s nucleus occurs.

______________________ Until the sister chromatids in each duplicated chromosome separate during

mitosis, they are held together by a protein ‘button’.

______________________ A chromosome is made up of two identical coiled strands of DNA.

______________________ Following mitosis, the division of a cell’s cytoplasm occurs.

______________________ Most cells go through a cyclical process of growth, development and division.

______________________ For most unicellular organisms, identified as those without a nucleus, the cell

cycle might be as short as a few hours or a few days.

______________________ The cell cycle can be divided into two main phases – a period of growth and

development and the mitotic phase.

______________________ Mitosis and cytokinesis result in the formation of two identical new cells.

______________________ For some cells, identified as those with membrane-bound nucleus, the cell cycle

might take as long as one year.

______________________ Prokaryotic cell division is asexual reproduction producing two identical daughter

cells.

______________________ A fertilized egg is a single undifferentiated cell.
