Different Types of Asexual Reproduction
~Fragmentation
~Binary Fission
-Longitudinal Binary Fission
-Transverse Binary Fission
-Irregular Binary Fission
~Budding
~Parthenogenesis
_________ is a type of reproduction where one organism is divided into _________
~Fragmentation
~minor fragments
___ results in new individual organisms
___ regrowing of lost body part
~fragmentation
~regeneration
_________ is the separation of the parent cell into ______________
~Binary Fission
~two new daughter cells
Binary fission
This process happens with the division of the parent’s genetic material into ___________. Each daughter cell receives ______ copy of its parent ________
~two parts
~one
~DNA
Process of Binary Fission
- Parent cell
- DNA duplicates
- Cytoplasm divides
- Daughter cells
_________ are microscopic __________ that have a relatively __________ and carry out __________. Some are free-living while others are parasitic

examples of protozoa
Paramecium
Amoeba
Euglena
Types of binary fission and sample
Longitudinal binary fission- Euglena
Transverse binary fission- Paramecium
Ireggular binary fission- Amoeba
___________ is when a new organism is developed from a small part of the parent’s _____. A ____ is formed detaches to develop into a new organism -.
~Budding
~body

- Chain of buds
Process of Budding in Blue-green algae (cyanobacterium)
- Vegetative cell
- Cell enlargement and formation of “Constriction”
- Two identical individuals
Process of budding in hydra
- Parent hydra
- Developing bud
- New bud
- New Hydra
