research lab 3 - Essay Exampleulum and golgi apparatus are located closer to the blood plasma membrane delinquent to their functions of self-destruction, releasing toxic substances to the outside environment and collecting waste products.The foundation in the structure of the plasma membrane is the phospholipid bilayer forming a barrier between two aqueous compartments on the two sides of the cell inner(a) and outside. There are specific functions for proteins embedded in the interior of the phospholipid bilayer. They carry out various functions much(prenominal) as selective transport of molecules and cell to cell identification. Thus, the main function of the plasma membrane is to pick up the active and passive movement of various substances into and out of the cell.Another major difference is that plant cells realize chlorophyll which is a light-absorbing pigment required for photosynthesis. Chlorophyll is responsible for giving the plants a green intensityand is found in c hloroplasts.However, golgi apparatus, lysosomes and peroxisomes are only found in eukaryotic cells due tothe fact that there are no membranous structures within the prokaryotic cellsexcept the plasma membrane. Mitochondria are known as the power plant of the cell because they are responsible for synthesizing most of the energy supply for the cell. This energy is in the form of adenosine triphosphate (ATP). Mitochondria are also responsible for producing cholesterol and heme and in the self-destruction mechanism of the cell. Mitochondria wipe out circular DNA which replicates similar to bacteria by a reproductive process called fission, they can wanton their own proteins.Moreover, as the structure always relate to the function, the presence of double membrane, i.e. a smooth outermost membrane and an inner membrane which has many folds known as cristae. The cristae increase the surface area thereby they enhance productivity of cellular respiration.Plant cells are known to be rigid structures with a delineate shape which is due to the
