Eukaryotic cell
Animal and plant cell
Prokaryotic cell
Bacterial cell
Nucleus
Control cell activities and retain chromosomes
Nuclear membrane
Double membrane with pores that allows transport of MRNA and Nucleotides
Chromatin
Coils of DNA which are bound to proteins (histones) and condense into chromosomes during cell division
Nucleolus
Makes RNA, which is needed for ribosomes
Mitochrondria
Site of aerobic respiration
Cristae
Inward folds of the double membrane that provide greater surface area for chemical reactions
Matrix
Organic 'matrix' of numerous chemical compounds (DNA, Ribosomes)
Ribosome
Protein synthesis
Endoplastic reticulum
Allows transport of materials through the cell
Rough ER
Has ribosomes on outer cellTransports proteins made by ribosomes
Smooth ER
No ribosomes on membrane Synthesise and transport lipids
Function of Golgi body
Modification and packaging of proteins for excocytosis
Formation of Golgi body
End of rough ER is pinched off from the ends to form small vesicles that join together to form Golgi body
End of Golgi body
End of golgi body is pinched off to form vesicles that secrete their content via exocytosis when they fuse with cell membrane
Lysosome
Contain digestive enzymes
Digestive enzymes
Destroy worn out organelles
