How many membranes do each cell organelle have?

Moin,

so to mention just a few examples:

The Cells and mitochondria for example a double membrane which consists of an inner and an outer core membrane.
However, in the mitochondria, the membrane encloses the entire organelle and the inner membrane is notched in various folds (Cristae)

The endoplasmic reticulum there are among other things the rER and the sER. The rough and smooth endoplasmic reticulum has membrane which is covered with ribosomes. However, the smooth endoplasmic reticulum (sER) does not have ribosomes, as a result of which it also appears “smooth”.

In conclusion, Vakuole (for the plant world) which large cell vacuols with in each case one membrane that is also called loving toneoplast.

I hope this helped you.

Greetings
