pmatc and interphase

Question 1

G1

Answer 1

Cell growth, organelle synthesis & SPECIFIC
life functions!

Question 2

S:

Answer 2

DNA Replication, histone synthesis.
(formation of “sister chromatids”)

Question 3

G2:

Answer 3

Centriole duplication, proteins form for
microtubule creation, final prep for division.

Question 4

Prophase:

Answer 4

Longest phase of mitosis.
* Chromatin condenses into
chromosomes (visible under compound light
microscope.)
* Nuclear membrane & nucleolus
disintegrate.
* Centrioles migrate to the poles.
* Spindle fibers form (microtubules that
help separate chromosomes!)

Question 5

Metaphase:

Answer 5

*Spindle fibers attach to
sister chromatids @ the
centromere.
*Spindle fibers pull
chromosomes into a single
file line along the middle of
the cell.

Question 6

Telophase:

Answer 6

*Chromosomes unwind
into chromatin. (NOT visible
under microscope.)
*Spindle fibers disintegrate.
* Nuclear membrane & nucleolus reform.

*Leads to cytokinesis…

Question 7

Anaphase:

Answer 7

*Spindle fibers pull sister
chromatids AWAY from
each other to opposite
sides of the cell.

Question 8

Animal Cell Cytokinesis:

Answer 8

• Cell membrane pinches
  in as cleavage furrow
  forms.
• 2 smaller, identical,
  diploid daughter cells
  formed!

Question 9

Plant Cell Cytokinesis:

Answer 9

*Cell plate forms during cytoplasmic division in order
to create a new cell wall.
