Self quiz on Organelles • Name all the organelles • Name all the organelles – Nucleus – Ribosomes – Endoplasmic reticulum (rough and smooth) – Golgi Complex – Mitochondrion – Lysosome – Centriole • To make sure you understand the function ask yourself what would happen to the cell if each one of the organelles disappeared from a cell – Nucleus – Ribosomes – Endoplasmic reticulum (rough and smooth) – Golgi Complex – Mitochondrion – Lysosome – Centriole • Nucleus – If there were no nucleus, DNA would be all over the cell and unprotected, it would be very hard to control gene expression • Ribosomes – Without ribosomes the cell would not be able to make any protein • Rough endoplasmic reticulum – Without the rough ER, cells would be unable to export proteins. • Sooth endoplasmic reticulum – Without the smooth ER, cells would not be able to make lipids or steroids • Golgi complex – Without the Golgi complex, cells would have a hard time sorting the molecules it needs to export. Also, there would be no lysosomes • Mitochondrion – Without the mitochondrion, the cell would not have enough ATP to function • Lysosome – Without lysosomes, the cell would be filled with waste and debris, and would be unable to get rid of its waste • Centrioles – Without centrioles it would be difficult for the cell to complete mitosis or meiosis due to the absence of the mitotic spindle. There would also be problems with cytokinesis
