16
Q

Metaphase

A

Chromosomes align in the middle of the cell before being separated into two daughter cells.

17
Q

Anaphase

A

Chromosomes split and the sister chromatids move to opposite poles.

18
Q

Telophase

A

Two nuclei form in new cells and the chromosomes begin to unwind into chromatin again.

19
Q

Cleavage furrow

A

The indentation on the cells surface which begins cleavage (process that many cells use for cytokinesis.)

20
Q

Cell plate

A

Formed during the cytokinesis of plants.

21
Q

Diploid

A

Cells have two homologous pairs of each chromosome.

22
Q

Binary Fission

A

Produces two separate cells, populations or species. Fission is the subdivision of a cell in which those subdivision regenerate into full cells.
