The cytoplasm refers to the inner contents of a cell excluding the nucleus. For a eukaryotic cell this includes membrane-bound organelles, the cytoskeleton and cytosol. The term cytosol only refers to the semifluid substance in which the inner components are suspended.
Cytoplasm of these cells would typically contain:
Membrane bound organelles
- Rough and smooth endoplasmic reticulum
- Golgi apparatus
- Secretory vesicles
Plants cells in addition to many of the components of animal cells also contain chloroplasts for photosynthesis and most mature plant cells also have a single large food vacuole. This is sometimes referred to as the central vacuole .
Prokaryotic cells (Prokaryotes)
Prokarya are all in all much simpler cells, and their cytoplasm would typically consist of ribosomes, cytosol, the cytoskeleton and inclusions (insoluble substances).
