The endomembrane system is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins. It includes a variety of organelles, such as the nuclear envelope, endoplasmic reticulum, Golgi apparatus, vesicles, endosomes, and lysosomes.

1. Nuclear Envelope: This is the membrane that encloses the nucleus. It serves to separate the contents of the nucleus from the rest of the cell.

2. Endoplasmic Reticulum (ER): This is a network of membranous tubules within the cytoplasm of the cell. It is divided into two types: Rough ER, which has ribosomes on its surface and synthesizes proteins, and Smooth ER, which is involved in lipid synthesis and detoxification processes.

3. Golgi Apparatus: This organelle is responsible for modifying, sorting, and packaging proteins and lipids for transport to targeted destinations.

4. Vesicles: These are small, membrane-enclosed sacs that transport and store substances within a cell from one cell to another.

5. Endosomes: These are vesicles that have been pinched off from the plasma membrane and function in transport within the cell.

6. Lysosomes: These are vesicles that contain digestive enzymes and can break down waste materials and cellular debris.

The endomembrane system is a complex and dynamic player in the cell's compartmental organization.
