What process does a multicellular organism use to replace its damaged body cells?
mitosis
meiosis
replication
transcription
Which of the following statements correctly describes the function of cell division in unicellular organisms?
Cell division allows the organism to grow.
Cell division allows the organism to reproduce.
Cell division allows the organism to produce sex cells.
Cell division allows the organism to repair damage to the cell.
Why does cell division take place in single-celled organims?
in order for the organisms to grow
to reproduce and pass on genetic information
to enable the organisms to heal injured tissues
to make specialized cells for different functions
Which of these lists presents the stages of the cell cycle in the correct order?
interphase, mitosis, cytokinesis
cytokinesis, mitosis, interphase
mitosis, interphase, cytokinesis
interphase, cytokinesis, mitosis
How would living things differ if cell division took place only for reproduction?
All living things would be single-celled.
Multicellular organisms would be much smaller.
Living things would be more genetically diverse.
Multicellular organisms would be unable to repair damaged cells.
Interphase is the longest stage of which process?
mitosis
cell cycle
cytokinesis
reproduction
Alli uses a microscope to look at slides of onion cells. The slides show the stages of the cell cycle. The slides are labeled and in the correct order, starting with interphase. In which slide would Alli first see chromosomes?
anaphase
prophase
telophase
cytokinesis
Which of these statements most likely describes what happens if DNA is not duplicated during interphase?
The new cells would be more numerous.
The new cells would have too many chromosomes.
The new cells would have too many or too few nuclei.

How does a mulitcellular organism grow larger?
Multicellular organisms do not grow larger.
Individual cells in the organism grow larger.
The organism gains new cells from other organism.
Cells in the organism divide, increasing the total number of cells.
In what way is cell division important to keeping organisms healthy?
Cell division makes specialized cells.
Cell division causes cells to grow larger.
Cell division replaces damaged cells with new cells.
Cell division is not part of keeping organisms healthy.

Which is the phase of mitosis in which the chromosomes line up across the center of the cell?
anaphase
prophase
metaphase
telophase
Which is the phase of mitosis in which the chromosomes in the nucleus of a cell condense and each chromosome consists of two chromatids held together by a centromere?
prophase
anaphase
metaphase
telophase
Which is the phase of mitosis in which the the chromotids or chromosomes move to opposite ends of the cell and two nuclei are formed?
prophase
metaphase
anaphase
telophase
