cell structures Flashcards
cell nucleus
the control centre of the cell that contains chromosomes of DNA
plasma membrane
semi permeable membrane that holds the cell together
controls entry and exit of materials into the cell (wastes, minerals)
cell wall
found only in plants: provides structure and support for cells
centriole
only in animal cells: forms spindle fibres for mitosis
chloroplast
only in plants: contains the chlorophyll, sight where photosynthesis occurs
chromosome
found in the cell nucleus, contains DNA to carry out all life processes
cytoplasm
holds dissolved foods and gases
endoplasmic reticulum
SA for reactions and transport system
golgi bodies
pack proteins that can be used by the body and transports them out of the cell
lysomes
collect cell wastes
mitochondria
site of respiration, produce ATP
nuclear membrane
outside membrane of nucleus
ribosomes
site of protein synthesis
vacuoles
store excess materials (more in plants)
