Cell Structure And Function

Question 1

Nucleus

Answer 1

Function:The control centre of the cell.
Contains DNA,which carries genetic information.
Nucleolus inside the nucleus produces ribosomal rRNA

Question 2

Mitochondria

Answer 2

Function:Powerhouse of the cell
Site of aerobic respiration,producing ATP from glucose and oxygen.

Question 3

Ribosomes

Answer 3

Function:Sites of protein synthesis
Can be found free in the cytoplasm or attached to the rough endoplasmic reticulum.ER
Made of rRNA and proteins

Question 4

Endoplasmic reticulum

Answer 4

Rough ER

Function:Studded with ribosomes,involved in protein and synthesis and modification.
Transports proteins to the Golgi apparatus.

Question 5

Smooth ER

Answer 5

Function:Lacks ribosomes,Involved in lipid synthesis,detoxification and calcium ion storage.

Question 6

Golgi Apparatus

Answer 6

Function:The processing and packaging centre of the cell.
Modified proteins received from the rough ER.
Packages proteins in to vesicles for transport to the destinations.
Inside/outside of the cell.

Question 7

Lysosomes

Answer 7

Function:The digestive system of the cell.
Contains enzymes that break down waste materials and cellular debris.
Important for an autophagy(Removing damaged organelles and apoptosis.
