Introduction
Fission - subdivision of cell into two or more parts and regeneration of those parts into separate cells.
Pre-Requisites:
Trying to understand what type of reproduction is fission.
Activity:
Videos which show how fission occurs
Real Life Question:
Which organisms undergo fission?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Fission | It is asexual reproduction and cell division used by prokatyotic organisms. Fission produces two separate cells. The cells produced are genetically identical. Eg - bacteria |
| Multiple fission | produces more than 2 separate cells. Eg - protists |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| microscope | Bacterial fission can be observed under microscope. |
Real life uses :
Bacteria multiplies using this type of reproduction which is harmful as it can cause diseases but also useful because some bacteria are helpful to humans
Places to visit :
