Cellular organelles are the internal organs of a cell. They are responsible for keeping the cell alive. They do this by bringing in food for the cell, getting rid of waste, protecting and repairing the cell, and helping it grow/reproduce.
The following provides the best argument for separating Archaea and Bacteria into their own domains instead of leaving them together in the single kingdom, Monera :
<u>It was discovered that they make their membranes differently and copy their DNA differently.</u>
Explanation:
The reason that Archaea were determined to be a separate kingdom so late was because archaea often completely resemble eubacteria. But you can see that fungi and other eukaryotes are more similar to archaea than the bacteria.
Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids
Bacteria: cell membrane contains ester bonds; cell wall made of peptidoglycan; have only one RNA polymerase; react to antibiotics in a different way than archea do
Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles.
Both archaea and bacteria have flagella, thread-like structures that allow organisms to move by propelling them through their environment.
In all organisms, cell membranes are made of molecules known as phospholipids.
The phospholipids of archaea are unusual as they have membranes composed of glycerol-ether lipids, whereas bacteria and eukaryotes have membranes composed mainly of glycerol-ester lipids
The offspring created by bacteria with this gene will be resistant to the medication. The reason is that the bacteria reproduce by binary fission. If anyone carries a gene which makes it resistant to antibacterial medication.
Then its offspring will be resistant because in binary fission, DNA replicates and seperate. DNA replicates which possess the gene which makes it resistant to antibacterial medication then offspring will have that DNA which possesses such gene. Binary fission is a type of asexual reproduction.
