characteristics of prokaryotic and eukaryotic cell

What are the 5 types of flagella?

1) Monotrichous 2) Amphitrichous 3) Lophotrichous 4) Peritrichous 5) Atrichous

The majority of gram-negative organisms have this cell wall structure

1) cell membrane 2) lipopolysaccharide (LPS) this is an endotoxin

What does monotrichous mean?

It is a polar cell with a single flagellum on the end of the cell

What do chromatophores do?

Make pigment colors

The nucleus contains this

DNA

What does Lophotrichous means?

Has small bunches or tufts of flagella emerging from the same site

What does Amphitrichous mean?

Having a single flagellum on both ends of the cell

What does Atrichous mean?

Without flagella

What are the six shapes of prokaryotic and eukaryotic cells?

1) coccus 2) bacillus 3) vibrio 4) spirillum 5) spirochete 6) pleomorphism

What are the five arrangements of prokaryotic and eukaryotic cells?

1) diplo 2) strepto 3) staphylo 4) tetra 5) sarcinae

What are some characteristics of eukaryotic cells?

1) they have a nuclear membrane around their DNA 2) their DNA is wound around histones 3) they have complex membrane-bound organelles

What are the characteristics of prokaryotic cells?

1) they have no nuclear membrane 2) their DNA is not wound around histones 3) the cell walls are made of a chemical called peptidoglycan 4) they do not have complex membrane-bound organelles

The majority of gram-positive organisms have this cell wall structure

1) trichroic acid 2) cell membrane 3) peptidoglycan (Murien)

What is a slime layer?

A diffuse unorganized layer of polysaccharides and/or proteins on the outside of some bacteria

What is a glycocalyx?

A filamentous network of carbohydrate rich molecules that coats cells

What is a capsule?

A hardened slime layer. Most of the bacteria that cause pneumonia make a capsule

What does Peritrochous mean?

Having flagella dispersed randomly over the surface of the cell
