CELL ORGANELLES Flashcards
important in the exchange of materials between the cells interior and the environment surrounding it
plasma membrane
rod-shaped organelles with a double membrane
mitochondria
site of protein synthesis in cell / smallest of the organelles
ribosomes
organelle composed of a network of enclosed channels
endoplasmic reticulum
has attached ribosomes & associated with the nucleus and produces proteins
rough er
does not have ribosomes & distal extension of rough er
smooth er
receives material from the enodplasmic reticulum
& other parts of the cytoplasm
golgi apparatus
digest materials with enzymes in a process known as phagocytosis
lysosome
bounded by nuclear envelope which is a double membrane
nucleus
contains nuclear pores & allows movement of materials into or out of the nucleus
nuclear envelope
membrane-bound sacs inside the cell
vesicles
cell consists of how many main parts?
2 (plasma & cytoplasm)
fluid in which the organelles are suspended
cytosol
inner fluid portion
cytoplasm
inner framework of the cell
cytoskeleton
