Anaphase
Telophase
Cytokinesis
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.

Some of the mitotic figures
marked are
a. Anaphase
b. Prophase
c. Interphase
a.
Anaphase
b.
Prophase
This is late TELOPHASE
at the arrow. Why is this
a TELOPHASE figure?
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.
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)?
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
What is each phase of the Blastula (white fish)?

PROPHASE
is characterized by well-formed
chromosomes and a nuclear
envelope that is dispersing
METAPHASE is characterized by
chromosomes lined up in single
file in the center of the cell.
ANAPHASE
is characterized by two
groups of chromosomes
moving towards the opposite
poles of the cell.
TELOPHASE is characterized by nuclei that
have reached the poles of the cell
and the onset of cytokinesis.
