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

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
