What do metachromatic granules contain?

Is it the proteins or the fatty acid tails which are responsible for giving the "Fluid Mosaic Model" of the plasma membrane its MOSAIC portion of the name?

Dormant, resistant structures in bacteria.

The term for bacteria which have a cluster of flagella at one or both ends.

The term for flagella that are spread evenly around the surface of the bacterium.

The term for bacteria that have a single flagellum at each end.

A glycocalyx that easily sluffs off, loosely attached.

A cell with an internal salt concentration of 0.1% salt is placed in a solution of 2% salt solution. Is the solution surrounding the cell considered hypotonic or hypertonic?

Adjacent rows of NAG and NAM are crosslinked by these.

This is the diffusion of water.

In a solution consisting of salt dissolved in water, which is the solute?

When a substance is chemically altered as it is moved across the plasma membrane.

Do gram positive cells have thick or thin peptidoglycan layers?

This method of moving molecules across the membrane uses proteins embedded in the membrane, but does not use ATP energy. It also moves molecules down the concentration gradient.

Gram negative cells appear _____ after the gram stain procedure.

Name the 3 genera which form endospores.

Do gram negative cells have thick or thin peptidoglycan layers?

A cell with an internal salt concentration of 0.1% salt is placed in a solution of 2% salt solution. Which way will water move, into or out of the cell?

Water loss from a bacterial cell, and the plasma membrane pulls away from the cell wall is called _______.

Plural form of the round or spherical shape of bacteria.

The term for membranes which allow some molecules to pass through while blocking passage of other molecules.

Plural form of the rod or capsule shape of bacteria.

Which region of the phospholipid molecule is hydrophobic?

When the solute concentration is greater.

The major bacterial genus that has bacteria with axial filaments.

What is the term for the outer membrane in gram (-) cell walls?

Gram positive cells appear _____ after the gram stain procedure.

Gas vacuoles are common in what type of bacteria?

The term for one polar flagellum.

This method of moving molecules across the membrane uses proteins embedded in the membrane, and uses ATP energy to move molecules against (up) the concentration gradient.

The prefix that identifies long chains of cells.

The prefix for pairs of bacteria stuck together.

Lipid A of the LPS layer of gram (-) cells acts as _______.

Does diffusion move molecules down or up the concentration gradient?

When the solute concentration is less.

How many rings are contained in the basal body of gram positive bacteria?

Which region of the phospholipid molecule is hydrophyllic?

The prefix that identifies grapelike clusters of cells.

Is the glycerol head of a phospholipid molecule polar or non-polar?

The two monosaccharides which form the sugar backbone of the cell wall peptidoglycan.

The type of bacterial appendage (fine, hairlike) used for ATTACHMEMT, not mortility?

O Polysaccharide of the LPS layer of gram (-) cells acts as _______.

Another name for passive transport.

What molecules are found in gram positive cell walls and NOT in gram negative?

How many rings are contained in the basal body of gram negative bacteria?

The type of filaments which wrap around the bacterial cell and give it a corkscrew type movement.

Name 2 unique amino acids found in the peptidoglycan of bacterial cell walls.

Equal solute concentrations.

The appendage used for conjugation in bacteria.

The portion of the flagellum that links the filament to the basal body.

A firmly attached glycocalyx.
