Question about organelles in a cell

[jjjjj]

OK if organelles are recycled in the cell when they're worn out does that mean that the parts that make up organelles never leave the cell???

Recycled? That is a wrong term. The organelles are repaired. And when a major organelle is worn out lysosome digests it and the cell is dead. From big I meant something like mitochondria.

I read that organelles are digested and reused by lysosome.

recycled is not too bad a term. In most organelles you have ongoing replacement (turnover) going on. Whether they ever leave the cell is kind of a philosophical question. The components of the membrane are replaced on a regular basis, for instance. The C-bodies are eventually oxidized to CO2 or volatile fatty acids that may be secreted (depending on cell type). As such they get out of the cell. However, the membrane as a whole persists.

if theyre recycled would that mean that they dont leave (the inside organlees)
