* Lysosomes: These are membrane-bound organelles that contain enzymes for breaking down waste materials and cellular debris.
* Golgi apparatus: This is a stack of flattened sacs involved in processing and packaging proteins and lipids.
* Endoplasmic reticulum (ER): This is a network of interconnected membranes that play a role in protein synthesis, lipid metabolism, and detoxification.
* Vacuoles: These are large, fluid-filled sacs that store water, nutrients, and waste products.
* Peroxisomes: These are small, membrane-bound organelles that contain enzymes for breaking down fatty acids and detoxifying harmful substances.
* Mitochondria: While having a double membrane structure, the inner membrane is highly folded, creating a single, continuous, highly convoluted compartment within the organelle. This is often considered a single membrane.
* Plasma membrane: The outer boundary of the cell, also known as the cell membrane, is a single phospholipid bilayer.
It's important to note that some structures, like the nucleus, have a double membrane.
