Lecture 1

Question 1

Spontaneous generation

Answer 1

Formation of a living organism without the decent from a similar organism. Randomly appears. (Beer rags and mouse appear)

Question 2

Pasteurization

Answer 2

Heating an object so it doesn’t form bacteria from the outside environment. This disproves spontaneous generation.

Question 3

Endospore

Answer 3

Dense protein that can survive when boiled

Question 4

Coat (Spore Coat)

Answer 4

Ring around the cortex that is dry so it causes the endospore not to be damaged by heat. Combination of spore specific proteins.

Question 5

Cortex

Answer 5

It is the spongy part of the endospore. It soaks up the water and keeps the spore dry.

Question 6

Core (Core Wall)

Answer 6

Contains the cell wall of the endospore and is very resistant.

Question 7

Prokarya

Answer 7

Singled cell organism that doesn’t have a bound nucleus.

Question 8

Bacteria

Answer 8

A large domain or kingdom. 90% of cells in the body. Prokaryote

Question 9

Peptidoglycan

Answer 9

Forms the cell wall of bacteria

Question 10

Archaea

Answer 10

Prokaryote. Has many extreme lifestyles. It is a kingdom or domain

Question 11

Eukarya

Answer 11

Multi-cell organism. Contains a cell wall and membrane bound organisms.

Question 12

Membrane-bound organelle

Answer 12

Organelles are not free in the cell

Question 13

Algae

Answer 13

Uses chloroplast for photosynthesis, can have cilia

Question 14

Fungi

Answer 14

Has 2 life forms: yeast and mold

Question 15

Protozoa

Answer 15

Uses endocytosis for feeding, can have cilia

Question 16

Endocytosis

Answer 16

Engulfs food

Question 17

Cytoskeleton

Answer 17

Makes up the structure of all cells and holds everything together

Question 18

Virus

Answer 18

Nonliving, either have DNA or RNA, a protein coat, and some have an encelope

Question 19

Bacteriophage

Answer 19

A virus that infects and replicates within bacteria

Question 20

Kingdom-specific infection

Answer 20

Viruses don’t cross infect. A certain virus only affects one type of kingdom(domain)

Question 21

Viroid

Answer 21

Infectious RNA. Infects the replicating process and the strand of DNA can not replicate and dies

Question 22

Prion

Answer 22

Infectious protein.Protein folds the wrong way and creates a template for the wrong protein.
