Prokaryotic Cells

Question 1

What does prokaryote mean?

Answer 1

Organisms whose cells lack a nucleus and other membrane bound organelles
Genetic material is in the form of a molecule of “circular” double stranded DNA

Question 2

Cell wall function

Answer 2

Physical barrier, excludes some substances
Protects against mechanical damage and osmotic lysis

Question 3

What does the cell wall contain?

Answer 3

Murein, a glycoprotein

Question 4

Cell surface membrane function

Answer 4

Semi permeable, controls what goes in and out

Question 5

Ribosomes size

Answer 5

70s, small, simple

Question 6

Ribosome function

Answer 6

Protein synthesis

Question 7

Circular strand of DNA

Answer 7

Carries genetic information for replication of bacterial cells by the process of binary fission

Question 8

Plasmid function

Answer 8

Contain genes that aid survival

Question 9

Capsule function

Answer 9

Protects from other cells
Helps bacteria stick together for protection

Question 10

Flagella function

Answer 10

Used for locomotion

Question 11

Virus

Answer 11

Acellular, non living particles
Contain nucleic acids enclosed in a protein coat or capsid
Only replicate inside living host cells
May be surrounded by lipid envelope
Capsid or envelope have attachment proteins that allow the virus to identify and attack to host cells
