Front 9

Cytoplasmic Membrane

Back 9

(plasma membrane) controls what comes into and leaves the cell bc its a semipermiable membrane.

Front 10

active transport

Back 10

pumping mechanism to transport stuff in and out of cell

Front 11

Cytoplasm

Back 11

contains all the machinery that allows the cell to grow and produce a new copy of itself (all the stuff inside the cytoplasmic membrane)

Front 12

Ribosomes

Back 12

enzymes that perform translation

Front 13

granules (inclusions)

Back 13

provide an energy source and available for special needs

Front 14

cell wall

Back 14

made of petidoglycan (a polysccharide); shapes and strengthens cell to prevent lysis; forms a fish net like structure (LYSOZYME breaks down PG)

Front 15

Capsules

Back 15

glycocalyx or sugar coat covering; makes the cell sliperry to avoid capture by WBC; makes it difficult for antibodies to bind to the cell

Front 16

cell envelope is comprised of

Back 16

cytoplasmic membrane and cell wall

Front 17

fimbrae

Back 17

hairlike appendages on the external surface; to hold onto host cells

Front 18

sex pilus

Back 18

for gene transfer (only has 1 or 2)

gram neg

Back 20

3 layered cell walls

4 STEPS OF GRAM STAINING

Back 21

1. stain with the primary, crystal violet
2. fix the vyrstal violet with iodine so it aggregates
3. wash the aggregates from the porous gram neg bacteria with acetone
4. counterstain with safranin so the gram neg cells are readily visible
