As you enter, on the scrap
piece of paper, write down all
the words that come to mind
when I say the word
“Reproduction”
Have your homework out to be
checked
Asexual Reproduction- one parent cell
divides into 2 daughter cells with the exact
same genetic information.
Type of
Asexual
Reproduction
Definition
Binary Fission
One-celled organism divides
by mitosis to form two
daughter cells.
Budding
Outgrowth of parent
organism. Duplicate of
parent.
Sporulation
Specialized cells are created
that contain a nucleus and a
small amount of cytoplasm and
have a tough protective coat
Regeneration
New organism from a part of a
parent organism.
Vegetative
propagation
PLANTS: Part of a plant is
grown into a new, duplicate
plant
Examples: Runners, Bulbs,
Tubers, Rhizomes, cuttings,
Grafting.

Examples
Mitosis- from 1 to 100
Why Cells Divide
Reproduction- Binary fission in
prokaryotes (bacteria no cell nucleus)
Growth- production of new somatic (body)
cells
Repair- Wound healing
The Cell Cycle
M- Phase (Mitosis)
INTERPHASE (Replicate): Genetic
information is copied and appear as
threads.
M Phase: (PMAT)
Prophase (condense): Mitosis
begins. Chromatin condense and you
can now see chromosomes. Nuclear
membrane breaks down.
Metaphase (middle): Spindle fibers
attach to centromere.
Chromosomes line up in the middle
of the cell
Anaphase (apart): Chromatids pull
apart to opposite polls.
Telophase (two new nuclei):
Spindle fibers disappear. Two new
nuclei form.
Cytokinesis (cytoplasm):
Cytoplasm splits into two new
daughter cells with identical
nucleus.
How is the cell cycle regulated?
Hormones and cell signals (proteins)
What happens if control of the cell
cycle is lost?
Cancer: uncontrolled mitosis.
• What – Teach Squared
• Why
– Continue to build neuron connectors
for long term memory
– Review MS learning
– Check to see what I need to study for LE Regents
– Opportunity to move while learning
• How
–
–
–
–
Each student gets an index card
Find 1 person to explain your term to
Other student explains his/her term
Together come up with 1 way both terms are similar OR
different
– Find 2nd person to explain your term to and repeat process
– Raise your hand up in the air with your index card if you
are looking for someone to teach
Read and color Cell Cycle &
Mitosis
• Read, color, and answer the questions.
• See Mrs. Geitner when you finish.
Closure
• Which part of the cell cycle is the most
important? Why?
