Jump to: navigation, search

Cellular compartments in cell biology comprise all closed parts within a cell whose lumen is usually surrounded by a single or double lipid layer membrane. Most organelles are compartments like mitochondria, chloroplasts (in photosynthetic organisms), peroxisomes, lysosomes, the endoplasmic reticulum, the cell nucleus or the Golgi apparatus. Smaller elements like vesicles, and sometimes even microtubules can also be counted as compartments.

In general there are 3 main cellular compartments, they are: 1. The nuclear compartment comprising the nucleus 2. The intercisternal space which comprises the space between the membranes of the endoplasmic reticulum (which is continuous with the nuclear envelope) 3. The cytosol hiiii
