Prokaryotic cells do not have internal membranous partitions. The latter occur in eukaryotic cells as covering of several cell organelles like nucleus, mitochondria, plastidsAll bio membranes are dynamic in nature, continually showing changes in their form, size, structure and function. Functions of the Cell Membrane. Both eukaryotic cells, including plant cells and animal cells, and prokaryotic cells, e.g. bacteria, are enclosedThe cell membrane is probably the most multifunctional cellular structure and has many functions that can be described in different levels of detail. Eukaryotic ribosomes A. Function: protein synthesis. B. Structure: Macromolecular complex of proteins and RNA.B. Structure: membranous vacuole/vesicle formed when the cell invaginates its plasma membrane to take up solutes/particles. Cell Structure Cell membrane (Plasma membrane) Eukaryote Both. Forms outer boundary of cellCell Structure and Function. Eukaryotic Cell: Neuron. Based on the organization of their cellular structures, all living cells can be divided into two groups: prokaryotic and eukaryotic (also spelled procaryotic and eucaryotic).The proteins and glycoproteins in the cytoplasmic membrane are quite diverse and function as Cell Structure and Function. Table 4.1 Differences between Eukaryotic and Prokaryotic cells. Eukaryotic cell (eu true, karyon nucleus) 1. Nucleus distinct, with well formed nuclear membrane.
