Micro: Chapter 3

A distinct thick gelatinous, sticky, sugary material that surrounds some microorganisms. It is a type of what?

An extraordinarily resistant dormant cell produced by some bacteria

Type of bacteria that have a cell wall characterized by a thin layer of peptidoglycan surrounded by an outer membrane; when Gram stained these cells are pink

Type of bacteria that have a cell wall characterized by a thick layer of peptidoglycan; when Gram stained, these cells are purple

Molecule that collectively makes up the outer layer of the outer membrane of Gram-negative bacteria

A macromolecule that provides strength to the cell wall; it is found only in bacteria

Gel-like material that fills the region between the cytoplasmic membrane and the outer membrane of Gram-negative bacteria

Cell surface structure type that allows cells to adhere to certain surfaces; some types are involved in a mechanism of DNA transfer

Extrachromosomal DNA molecule that replicates independently of the chromosome

Shapes: Cylindrical ______, Rod _______, Short Curved Rod ______, Long curved spiral (rigid, spring) ______, Long curved spiral (flexible) ______ Varied shape _______

Groupings: Cell(s) divide in 1 plane form _____ & _____, Cell divides in 2 or more planes perpendicular to one another form _______ Cell divides in many planes randomly. (give bacteria exammple for each grouping)

Multicellular Association: Upon starvation or limited water/nutrients some prokaryotic cells called myxobacteria come together to form a structure called a ___________ , a stalk-like structure

Multicellular Association: In their natural habitat, most bacteria on surfaces live in communities called ________

Prokaryotic Cell: the surface layers that consisit of the cytoplasmic membrane, cell wall, and if present, capsule are called the ___________

Prokaryotic Cells: ______ provides rigidity to bacterial cell walls preventing the cells from lysing
