I am not exactly sure, but i think organelles made when a cell is made, or reproduced. Organelles are a nesscesity of cells and just come when a cell is made.
Usually organelles are not repaired when they are broken. They simply get digested and recycled by the lysosome because the cell can always make more of a certain organelle.
Structure: A thin covering with pores. Function: Controls what substances come into and out of the; to protect the cell. Found: Just inside the cell wall(plant cell) Outer boundary(animal cell)....
