Appearance: Egg shaped-membrane bound structure.Contractile vacuole: removes water and wastes.Function:Storage of water, starch, fats, etc.Plant: usually 1 large water-filled vacuole(maintains structure).Appearance: Cavities filled with fluid.Function:Powerhouse of the cell (energy production ATP).Location: Many mitochondria in a cell!.Appearance: usually bean shaped with folded membranes (greater surface area-hence more energy).Function:Temporary storage, packaging and secretion of proteins and fats.

Location: Free in the cytoplasm attached to the ER -proteins made are used by the cell or moved out and used by other cells.

Smooth Endoplasmic Reticulum (Smooth ER)

Rough: acts like a conveyer belt and transports proteins.Location: Connected to the nucleus and plasma membrane.Appearance: mesh of hollow sheets with ribosomes attached.Rough ER Rough Endoplasmic Reticulum (Rough ER) Function:Controls materials in and out of the cell.Appearance: Round structure inside the nucleus.Function:Suspends organelles site of chemical reactions.Function:Control center for all cell functions.
