Term
What is the function of the Nucleus?
Definition
Its the largest organelle which contain the DNA for replication
Term
What is the function of the Lysosomes?
Definition
They contain a powerful digestive Enzyme
Term
What is the function of the Nucleolus?
Definition
The Nucleolus makes RNA and Ribosomes
Term
What is the function of the RER?
Definition
The RER contains ribosomes which make the proteins, which are then secreted off in vesicles
Term
What is the function of the SER?
Definition
It is involded with making Lipids
Term
What is the function of the Golgi Apparatus?
Definition
It recieve proteins and modifies them so they can be secreted out of the cell
Term
What is the function of Mitochondria?
Definition
It is where ATP is formed
Term
What is the function of Chloroplasts?
Definition
They are the site for photosynthesis
Term
What is the function of Ribosomes?
Definition
They are the site of Protein Synthesis
Term
What is the function of Centrioles?
Definition
During nuclear divison, they form spindal fibres to move the chromosomes
Term
What is the structure of Nucleus?
Definition
Its a largest Organelle
Term
What is the structure of the Nuclear Envelope?
Definition
Its made up of 2 membranes with fluid inbetween it They contain nuclear pores so large molecules can travel though them
