What is each stage of the Cell Cycle?

The ALLIUM (onion root tip) is a region of fast growing tissue where many cells are dividing at any given

moment. Furthermore, these plant cells have very nicely defined cell borders (cell walls) and unlike many animal

cells are easy to distinguish.

This is late TELOPHASE at the arrow. Why is this a TELOPHASE figure?

This shows a PROPHASE nucleus at (a). What

structure do you think is shown at (b)? Can you find another prophase

figure? How does it compare with that seen at

(a)?

In plants, telophase begins the moment you can first detect a

cell plate beginning to form, and it does so from the middle or

inside out, rather than pinching from the outside inward as in

animal cells.

Nucleus, the nuclear envelope has dispersed.

This shows an ANAPHASE cell at the arrow. What stage of mitosis is the cell next to it exhibiting? In what stage are

most of the cells seen here?

Metaphase, prophase

is characterized by well-formed chromosomes and a nuclear envelope that is dispersing

is characterized by chromosomes lined up in single file in the center of the cell.

is characterized by two groups of chromosomes moving towards the opposite poles of the cell.

is characterized by nuclei that have reached the poles of the cell and the onset of cytokinesis.
