Mitosis

12. A photomicrograph of cells involved in various stages of nuclear division is shown. Which title is most appropriate for this photomicrograph

/Mitosis in an Onion Root Tip

If the diploid chromosome number of a cloned plant is 12, the chromosome number of the plant cell used to produce the cloned plant is

12

Which mitotic event in the chart occurs after the other three events have taken place?

B Separation of chromatids by the action of spindle fibers

The diagrams shown represent stages of a cellular process. Which is the correct sequence of these stages?

B- D - C - A

The process of mitosis usually involves

DNA replication and separation of chromatids

Which statement best describes a difference between cell division in plant and animal cells?

In animal cells, cytoplasmic division is accomplished by "pinching in" of the cell membrane, while in plant cells a cell plate is synthesized.

The cell in the diagram below illustrates a stage of mitotic cell division.

centrioles

Normally, a complete set of chromosomes (2n) is passed on to each daughter cell as a result of

mitotic cell division

Normal mitotic cell division results in cach daughter cell having

the same number and kinds of chromosomes as the parent cell

Which is a characteristic of the group of diseases known as cancer?

uncontrolled cell division
