What is difference between bacteria and archaea?
Difference in Cell structure Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.
What are archaea made of?
In the case of bacteria and eukaryotes, membranes consist chiefly of glycol-ester lipids, but archaea have membranes made of glycerol-ether lipids. Ether bonds are chemically more stable than ester bonds, assisting archaea in survival at extreme temperatures and extreme pH environments.
What is the main difference between blue green algae and bacteria?
Cyanobacteria is also known as blue-green algae. They differ from other bacteria in that cyanobacteria possess chlorophyll-a, while most bacteria do not contain chlorophyll. Chlorophyll-a gives them their characteristic blue-green color.
What are the harmful effects of Archaebacteria?
Here are some harmful effect of kingdom archaebacteria: Producing sulfuric acid. Producing marsh gas. Promoting periodontitis.
What are the characteristics of an archaean organism?
Archaea, (domain Archaea), any of a group of single-celled prokaryotic organisms (that is, organisms whose cells lack a defined nucleus) that have distinct molecular characteristics separating them from bacteria (the other, more prominent group of prokaryotes) as well as from eukaryotes (organisms, including plants and animals,
Are there cell walls in bacteria and archaea?
Recent advances in electron microscopy also illustrated the presence of an outer(most) cellular membrane within several archaeal groups, comparable to the Gram-negative cell wall within bacteria.
Is the Archaea a single celled organism or prokaryote?
Archaea (/ ɑːr ˈ k iː ə / or / ɑːr ˈ k eɪ ə / ar-KEE-ə or ar-KAY-ə) (singular archaeon) constitute a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes.
Where does the name Archaea come from in Greek?
Archaea is derived from the Greek word archaios, meaning “ancient” or “primitive,” and indeed some archaea exhibit characteristics worthy of that name.
