IB Biology : Organelles and Compartmentalization

identify one of the main advantages of compartmentalization in cells

increased efficiency and specificity of cellular processes

the cell wall is not considered an organelle. identify the reason why

it does not have a specific metabolic function

why are the cytoplasm and nucleus separated in eukaryotic cells?

to prevent protein synthesis before post-transcriptional modification of mRNA

what is a possible disadvantage of compartmentalisation in cells?

it can delay a cells ability to respond to the environment

identify the function of the golgi apparatus

sorting of proteins

which of the following is an advantage of the organelles being separated from the cytoplasm?

the organelle can maintain its own internal environment

what is the destination of a protein synthesized by free ribosomes?

cytoplasm

what is the purpose of the double membrane in the mitochondrion?

to separate the intermembrane space from the cytoplasm

which of the following is correct with regard to the free ribosomes found in eukaryotic cells?

they synthesise proteins for use primarily within the cell

what is the benefit of the double membrane of the nucleus in maintaining the stability of genetic information?

it prevents the loss of DNA to the cytoplasm

what is the significance of the separation of the nucleus and the cytoplasm in eukaryotic cells?

it allows for better regulation of gene expression
