Organelles Flashcards
RER function
Has ribosomes
Site of protein synthesis
Structure of ER
A complex network of flattened bound sacs called CISTERNAE
SER
No ribosomes
Metabolic reactions
Synthesis of lipids and steroid
Golgi apparatus structure
Stack of membrane bound sacs
Function of GA
Package and modify proteins from ER
Prepare then for secretion
Ribosomes structure
Small organelles
Made of RNA
Ribosomes function
Carries out protein synthesis using nucleic acid
Mitochondria structure
Outer and inner membrane folded-> CRISTAE
Function of mitochondria
Site of aerobic respiration
Produces ATP
Structure of centriole
A pair of short cylinders
Each Cylinder is made of 9 microtubules
Function of centriole
Form a SPINDLE shaped structure of PROTEIN FIBRES on which Chromosomes can move during cell division
Flagella and cilia structure
Hair like extensions of the surface if the cell
9 microtubules abd 2 in mid
Flags longer
Flagella function
Causes whole cell to move
Microtubules use energy from ATP to slide over each other -> movement
