ER- blood vessels
microtubles- skeleton

chlorophlast -solar panel
centrioles

Your teacher sets strange homeworks, wouldnt it be easier and more useful for him just to get you to write definitions?

i've always found this type of exercise terribly unscientific. Sure, you can do some analogies to better understand the role of some organelles, but all the organelles in a cell do more than one thing. for example, the ER is not only a circulatory apparatus of the cell, it is also the site where membrane and secreted proteins are made, the site of disulfide bond formation, the site of the first protein modifications such as carbohydrate addition and signal peptide cleavage, the place where Calcium is stored, the place where most phospholipids are made etc. See what i mean?
