Document Summary

It contains the genetic inheritance for that cell in the form of instructions for all possible proteins the cell can make: the cytoplasm lls the space between the nucleus and the plasma, membrane. Organelles are part of the cytoplasm: the plasma membrane encloses the cell, separating the intracellular. The plasma membrane is semi- permeable (selectively permeable). This means it can allow some substances to cross while restricting the movement of others: the cytoplasm consists of three components, 1. Cytosol: a viscous uid in which the other components are suspended; consists of water plus proteins, salts, sugars, other solutes: 2. Organelles: structures that carry out the metabolic activities of the cell such as protein synthesis, atp production, digestion - we shall explore these next: 3. They bind messenger rna and transfer rna to synthesize polypeptides and proteins: endoplasmic reticulum - a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane.
