COMPONENTS OF CYTOPLASM:

1. Cytosol
2. Organelles
3. Cytoplasmic inclusions

CYTOSOL

• The soluble part of cytoplasm is the cytosol and forms the ground substance of cytoplasm.
• Chemically cytosol is 90% water forming a solution containing all the fundamental molecules of life.
• In cytosol, small molecules and ions may form true solutions and some large molecules form colloidal solutions.
• Colloidal solution may be a sol (non-viscous) or a gel (viscous). Peripheral parts of the cytoplasm are often gel like.
