  1. Cytoplasm
  2. Nucleus

CYTOPLASM:

Cytoplasm is the protoplasm of a cell outside the nucleus

COMPONENTS OF CYTOPLASM:

Cytoplasm has three main components which are
  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.
