Thus,under a microscope this particular section appears rough in texture.TheGolgi complexis series of interconnected flattened sacs (vesicles) located between the nucleus andcytoplasmic membrane.The Golgi complex serves as the ‘distribution center’ of the cell. Here, the proteins mayundergo modifications or be packaged before being distributed.Lysosomesare membraneenclosed organelles that contain hydrolytic enzymes capable of degradingunwanted cellular debris such as proteins, lipids, nucleic acids and polysaccharides. Thus, lysosomes serve asthe waste disposal system of the cell.Mitochondriaare double membraneenclosed organelles primarily responsible for generating ATP, a chemicalsource of energy within the cell. Thus, the mitochondria can be considered the ‘power house’ of the cell. Inorder to maximize its ‘power output’ mitochondria contain tightly packed folded internal membranes calledcristae to drastically increase the surface area where chemical reactions occur. The number of mitochondriamay vary between cell types ranging from 0 in red blood cells to > 2000 in liver cells.Chloroplastsare double membraneenclosed organelles specific to algae and plants and house thephotosynthetic pigment chlorophyll. Important to note, animal cells do not contain chloroplasts. Chloroplasts arethe site of photosynthesis—the process of capturing sunlight and converting it into the usable energy sourcesATP and NADPH.Figure 1.4. The prokaryotic cell. Arrows indicate key components of a prokaryotic cell. However, not all arealways found within a prokaryotic cell (i.e.) not all prokaryotes have a flagellum and/or pili.
