Micro Prokaryotic Cell For Exam 1

Front 1

Shapes of prokaryotic cells.

Back 1

a. Rods- Bacilli

b. Rounds- Cocci

c. Spirals-Suiburio, Sprillia,Spirochetes

Front 2

Prefix:

Back 2

Diplo- 2

Strepto- chain

Cluster- Staphylo

Front 3

Pleomorphica-->

Back 3

with no walls, many shapes

Front 4

Flagella: swimming movement

Back 4

Mono-trichous– single flagellum at one end Lophotrichous–small bunches emerging from the same site Amphitrichous–flagella at both ends of cell Peritrichous–flagella dispersed over surface of cell

Front 5

What is Fimbrie?

Back 5

Fine, protein, hairlike bristles

Function is sticking to other cells and surfaces.

Front 6

What is Pili?

Back 6

Rigid tubes made of pilin protein.

Front 7

what is Glycocalyx?

Back 7

Coatingof molecules external to the cell wall, made of sugars and/or proteins

• Twotypes:

1. Slim layer - loosely organized and attached

2. Capsule - highly organized, tightly attached•Theslim layer is for sticking onto surfaces

•Andthe capsule is for hiding from the immune system.

Front 8

Gram Positive Stain

Back 8

staining is purple Pos= Purple

Many thick peptidoglycan layers

Teichoic Acid

Front 9

Gram Negative Stain

Back 9

Thin peptidoglycan

Outer membrane

Lipotecichloic acid

with lipopoly saccharaide

Toxic immune response

Front 10

Plasma Membrane

Back 10

Gate keeper for material crossing inand out

Outer to inner communication

Sensations

Front 11

Cytoplasm:

Back 11

-water, protein (cytoskeleton- forms a gel and contains lots of enzymes ad nutrients and wastes, compounds that communicate.

Plasma membrane

Front 12

Ribosomes

Back 12

builds proteins out ofamino acids (about 20 different)

The RNA carries instructions that are made from the DNA to showthe order.

Front 13

Inclusion Granules:

Back 13

Store nutrients- glycogen and phosphates

Front 14

Nucleoid:

Back 14

Where gentic material is found, DNA area of the cell Primary center for DNA transcription, and replication occur Contain protein and enzymes and RNA. Always circular

Front 15

Endospores:

Back 15

Only in a few Gram positive pods

for survival in harsh climates, they will germinate when no longer needed.
