Organelles don't exactly make copies of themselves in the same way that DNA replicates. Instead, they grow and divide through a process called organelle biogenesis.

Here's how it works:

* Growth: Organelles increase in size by accumulating more of their specific components (proteins, lipids, etc.).

* Division: Once they reach a certain size, they undergo a process of division, creating two smaller organelles.

During mitosis:

* Pre-existing organelles are distributed between the two daughter cells.

* New organelles are also synthesized to ensure the daughter cells have enough for their own needs.

So, while not true "copying," organelle biogenesis and division ensure each daughter cell receives a sufficient number of organelles after mitosis.
