|
Mitosis
|
the division of the nucleus
|
|
|
chromosomes
|
-found in the nucleus
-chromosomes are composed of DNA. |
|
|
spindle
|
spindle fibers pull the chromatids to opposite poles during mitosis.
|
|
|
interphase
|
(not a part of mitosis) cell grows and organelles divide.
|
|
|
prophase
|
the chromatin condenses into chromosomes and spindle fibers start to form.
|
|
|
metaphase
|
the chromosome line up in the middle of the cell and the spindles attach.
|
|
|
Anaphase
|
the chromatids separate and the spindles pull the chromatids toward the poles.
|
|
|
Telophase
|
the chromatids begin to unwind and the nuclear envelopes form.
|
|
|
cytokinesis
|
(not a part of mitosis) the cytoplasm divides producing two identical daughter cells.
|
|
|
Mitosis in plant cells vs. animal cells.
|
in cytokenesis for plants a cell plate forms and in animal cells a cleavage burrow forms.

|
|
cell cycle
|
the time during which a cell grows, prepares for division, and divides to form two cells.
|
|
|
G1 phase
|
cell grows and gets larger.
|
|
|
S phase
|
synthesis = replication of chromosomes
|
|
|
g2 phase
|
replication of organelles and growth.
|
|
|
M phase
|
cell division
|
|
|
checkpoints
|
(before s, before m, and before the end of m) there the cell checks to make sure no fatal errors have occurred, if so, they fix them.
|
|
|
Binary fission
|
the cell replication of prokaryotes.
1) duplication of chromosomes (separate masses) 2) elongation 3) division |
