Cell Structure And Microscopy

Question 1

What is the difference between a eukaryotic and prokaryotic cell?

Answer 1

Prokaryotic:
-Single Cellular
-No membrane bound organelles
-No nucleus
-Peptidoglycan cell wall

Eukaryotic:
-Nucleus and Nucleolus
-Membrane bound organelles
-Multicellular
-Cellulose cell wall

Prokaryotic cells are smaller

Question 2

What is Endosymbiotic Theory?

Answer 2

A theory that states that mitochondria and chloroplasts were once separate prokaryotic organelles.

Question 3

What is the structure and function of the nucleus?

Answer 3

Structure: Surrounded by a double membrane
Function: Stores the organisms genome and transmits genetic information

Question 4

What is the structure and function of the nucleolus?

Answer 4

Structure: Has no membrane, contains RNA
Function: Makes ribosomes

Question 5

Structure and function of the nuclear envelope:

Answer 5

Structure: Are pores
Function: Separates the contents of the nucleus from the rest of the cell

Question 6

What is the structure and function of the golgi apparatus ?

Answer 6

Structure: Stack of membrane bound flattened sacs
Function: Proteins are modified

Question 7

What is the structure and function of the RER?

Answer 7

Structure: System of membranes, coated with ribosomes
Function: Intracellular transport system, provides large surface area for ribosomes

Question 8

What is the structure and function of the RER?

Answer 8

Structure: System of membranes, coated with ribosomes
Function: Intracellular transport system, provides large surface area for ribosomes

Question 9

What is the structure and function of the SER ?

Answer 9

Structure: System of membranes containing fluid filled cavities that are continuous with the nuclear membrane. No ribosomes
Function: Contains enzymes involved in lipid metabolism
