What is part A?What is its function?What is it made of?

A

Fimbriae

• Made of the protein pilin

• Used for attachment

What is the primary stain in the gram stain?

• Crystal Violet

• Gram positive therefore appear purple

What is the counterstain used in the gram stain?

• The counterstain is saffranin red

• Gram negative bacteria therefore appear pink

What is a glycocalyx and give two examples?

Glycocalyx

• “sugar coating”

• Capsule

• Slime Layer

Capsule stain

What are the four types of arrangements of flagella on a

bacterium?

Flagellar arrangements include:• Monotrichous• Lophotrichous• Amphitrichous• Peritrichous

This depicts a cell placed in what type of solution?

•This depicts a cell in a hypertonic solution

•The cell has undergone plasmolysis

This figure depicts what process?

Facilitated transport

•Substances are moving from a higher concentration to a lower concentration

•A transporter protein was needed

Name 3 types of passive transport

Name 3 types of passive transport

• Simple diffusion

Name 2 active processes used by prokaryotes to transport materials across the

cell membrane

Name 2 active processes used by prokaryotes to transport materials across the

cell membrane

• Active transport

• Group translocation

What are the major components of a cell membrane?

What are the major components of a cell membrane?

• Phospholipid bilayer• Proteins

What is the function of a plasmid?

What is the function of a plasmid?

• Plasmids are made of circular double-stranded DNA

• That contain important genes

• Give new characteristics to cells

• Some may be transferred to other bacteria

What is the function of ribosomes?

• Also describe their structure

Ribosomes

• Used for protein synthesis

• Are 70S in prokaryotes

• Are made up ribosomal RNA and proteins

• Contain a large and small subunit
