Introduction
Eubacteria are the ‘true bacteria’ generally known as bacteria.
Pre-Requisites:
What is Archaebacteria?
Activity:
Observe bacteria under microscope. All bacteria have a rigid cell wall, and motile bacteria have flagella.
Real Life Question:
Do bacteria make a difference to us?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Cyanobacteria Heterocysts Photosynthetic autotrophs Chemosynthetic autotrophs Heterotrophic bacteria Mycoplasma | Also known as blue-green algae. These bacteria are photosynthetic, autotrophic in nature. Specialized cells that the cyanobacteria can fix nitrogen in. Organisms that can make their own food and release energy in the form of ATP in the presence of sunlight. Organisms that produce ATP in the presence of chemicals like ammonia etc. Bacteria that are not capable of producing their own food. Organisms that lack cell wall and can survive without oxygen. These are the smallest living cells known. |
