Asexual Reproduction
uses genetic information (DNA) from only __________________________ (does not use sex cells {gametes})
offspring (__________________________) are exactly like the parent (__________________________)

Advantages
when an organism is __________________________________________________________________________

Disadvantages
when an ____________________________________________________________________________________

Types of Asexual Reproduction
1. Binary Fission
• __________________ (bacteria)
• Cell splits into ___________ parts
• Each part __________________ __________________of the
genetic info
• Each new cell is __________________ __________________
__________________
2. Budding
• __________________ and hydra
• Little __________________sprout from __________________
• __________________ cell division
3. Mitosis (Cell reproduction/division)
•
Some ______________________ organisms use mitosis for reproduction.
•
__________________, __________________organisms use mitosis to _________________________________
___________________________________ and to make _____________________________________________
•
For multicellular organisms, mitosis is part of the CELL CYCLE.
When a cell is NOT in mitosis, it is in ___________________.
Interphase include three sections…..
S - ______________________
G2 - ____________ mitosis, period of rapid
___________________, more _________________
and __________________. Getting ready for MITOSIS!
G1 - ______________ synthesis; more ______________
and production of __________________.
•
Mitosis can be divided into FOUR stages
1.
___________________ (P = prepare)
Chromatin in nucleus ___________________ to become
___________________, nucleolus and nuclear membrane fade,
____________________ move to opposite sides of the cell
2. ___________________ (M = meet/middle)
Centrioles arrive at __________________________ and
chromosomes line up in the ______________________.
_________________________ guide chromosomes to opposite
ends of the cell.
3. ___________________ (A = apart)
Connections between the copied chromosomes (_________________)
breaks and each copy moves to ____________________ of the cell.
4. ___________________ (T = tear/two)
Nuclear membrane and nucleolus _________________,
chromosomes _________________ to become
___________________.
•
Cytokinesis – occurs after completion of ________________; Stage in the cell cycle during which the
