What do the prokaryotic bacteria cell structures lack?
|
Prokaryotic cells lack nuclear membrane, mitotic apparatus: Bacteria do not have a membrane-enclosed nucleus. Their genetic material is located in an irregular region called the nucleoid. Bacteria do not have spindles and asters that make up the eukaryotic mitotic apparatus.
|
|
What do the prokaryotic cells do to make up for the fact that the bacteria do not have spindles and asters that make up the eukaryotic mitotic apparatus?
|
The prokaryotic cytoskeleton helps pull the replicated DNA apart.
|
|
Do the bacteria have typical eukaryotic organelles?
|
No. They lack typical eukaryotic organelles: Bacteria don't have Golgi, ER, mitochondria, chloroplasts.
|
|
How are bacteria classified by shape?
|
Major classifications of bacteria by shape: bacilli (rod-shaped); spirilli (spiral shaped); cocci (spherical); eubacteria; archae.
|
|
What are Eubacteria and Archaea?
|
Eubacteria is the bacteria we encounter every day, while Archaea is the bacteria that inhabits extreme environments (high salt, temperature, or chemicals).
|
|
What is the bacterial cell wall made up of?
|
The bacterial cell wall is made of peptidoglycan, a polysaccharide-protein molecule.
|
|
What are the plant and fungi cell wall made of ?
|
The plant cell wall is made of cellulose and fungi cell wall is made of chitin.
|
|
What is the bacterial flagella made up of?
|
Bacterial flagella is made of flagellin.
|
|
What is the eukaryotic flagella made up of?
|
The eukaryotic flagella is made of microtubules.
|
|
Explain mechanism of the bacterial flagella.
|
The mechanism of the bacterial flagella is rotation. A rotor at the base of the flagella drives the rotation, powered by a proton or sodium gradient.
|
|
What is the eukaryotic flagella powered by?
|
The eukaryotic flagella is powered directly by ATP.
