Cells Flashcards
What is a capsid
Protects the viral genome and can help in the attachment to the host cell
What is the nuclear envelope ?
Double membrane with nuclear pores that encloses the nucleus
What is chromatin
Diffuse threads which contain DNA and protein
What is the nucleolus?
A region which produces subunits of ribosomes
What are chromosomes ?
They house dna and chromatin
What are polyribosomes
Strings of ribosomes which simultaneously synthesise the same protein
What are lysosomes
Vesicles that digest macromolecules and cell parts
What are centrosomes?
Microtubules organising centre that contains a pair of centrioles
What is the cytoskeleton?
Maintains the shape of the cell
Assists in movements of cell parts
What is the cytoplasm
Semi fluid matrix that contains organelles
What is the plasma membrane
Outer surface that regulates the entrance and exit of molecules
What is the Golgi apparatus
Processes packages and secretes modified cell products
What’s mitochondrion
Organelle that carries out cellular respiration
Produces atp molecules
What are ribosomes
Particles which carry out protein synthesis
What the rough ER and smooth ER
Rough ER- studded with ribosomes. Processes proteins
Smooth ER- lacks ribosomes. Synthesises lipid molecules
