Webb27 jan. 2012 · Canaliculi in bones are cytoplasmic processes between bone cells that form between the bone cells (osteocytes) before the extracellular matrix hardens, or ossifies. WebbThe Plasma Membrane. Like prokaryotes, eukaryotic cells have a plasma membrane ( Figure 3.8) made up of a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. A phospholipid is a lipid molecule composed of two fatty acid chains, a glycerol backbone, and a phosphate group.
