Chapter 10 Review
 An
advantage of asexual
reproduction is provides genetic
diversity.
 During
cell division, each daughter
cell will get the same number of
genes is one advantage of having a
cell’s DNA bundled into separate
chromosomes.

 Centrioles
and centromere’s are
connected by microtubules.
A
parent cell containing 46
chromosomes will produce 2
daughter cells both containing 23
chromosomes.
 Cell
plates form during the cell
cycle to make the true division in
plant cells.
 G2
phase of mitosis is when DNA is
replicated.
 Each
half of a chromosome is called
an chromatid and held together at
the centromere.
 Spindle
fibers dissolve during
prophase and re-form during
telophase to break the daughter
cells apart.
A
cell with 10 chromatids in the G1 phase
will have 20 chromatids in the G2 phase.
 The
phase following telophase is
called G1, Interphase.
 As
a cell grows larger, the demands
on DNA has no affect on the cells
ability to carry out its functions.
 In
an environment that is stable
(remaining the same), organisms
that reproduce by asexual
reproduction, will fail because they
can’t adapt.
 The
cell cycle happens (in order):
Interphase, prophase, metaphase,
anaphase, telaphase.
 During
anaphase, centromere’s pull
the chromosomes apart into
chromatids by moving (shorting) the
spindle fibers.
