CHAPTER 4 GUIDE Flashcards
What are the parts of a bacterial cell from the outside inward?
Capsule,Fimbriae,Pili,Flagella,Cell Wall,Cell Membrane, Cytoplasmic Matrix, Cytoplasm, Glycocalyx, Ribosomes, inclusion Bodies,Nucleiod

What is the Capsule?
It is a polysaccharide layer that lies outside the cell envelope.

Is capsule part of the outer envelope of a bacterial cell?
Yes
What is the Nucleoid?
DNA/genetic information.

Is Nucleiod surrounded by a membrane?
No
What is the Cytoplasm?
It is where the functions for cell growth, metabolism, and replication are carried out.

What are Pili?
they are part of bacterial cell that transfer genetic information(conjugation).

What is the singular version of the Pili?
Pillus
Describe the Pili.
elongated tubes that has long tethers.

What are Fimbriae?
Velcro-like, short and numerous bristles

What do Fimbriae do?
stick to cells and surfaces
What is the Glycocalyx?
a glycoprotein and glycolipid covering that surrounds the cell membranes of some bacteria

What is the other term for Glycocalyx?
Pericelullar Matrix
What substance is the bacterial cell wall made of?
it is a rigid layer of polysaccharides
What is the Cell Membrane?
It is the actual barrier.

What are Ribosomes?
these are where protein synthesis occurs.

What are Inclusion Bodies?
storage sites

What is the other term for Inclusion Bodies?
Granules
What are Plasmids?
Extrachromosomal genetic units characterized by several features, is a double-stranded DNA that is smaller than and replicates indepently of the cell chromosome, it bears genes that are not essential for cell growth; it can bear genes that code for adaptive traits; and it is transmissible to other bacteria.

What is the typical size and shape of Plasmids?
They are usually small and circular.
What do Plasmids contains?
It contains non essential DNA and antibiotic resistance.
What is the Cytoplasmic Matrix?
the liquid found inside the cells.

Does typical bacterium have a cellular wall based on the cellular envelope?
Yes
Does non-typical bacterium have a cellular wall based on the cellular envelope?
No
