Yet, even before the beginning of the twentieth century, examination of stained sections of animal tissues hinted at the existence of an extensive membrane network within the cytoplasm. It wasn’t until the development of the electron microscope in the 1940s, however, that biologists began to appreciate the diverse array of membrane-bound structures present in the cytoplasm of most eukaryotic cells. These early electron microscopists saw membrane-bound vesicles of varying diameter containing material of different electron density; long channels bounded by membranes that radiate through the cytoplasm to form an interconnected network of canals; and stacks of flattened membrane-bound sacs, called cisternae.  \nIt became evident from these early electron microscopic studies and the biochemical investigations that followed that the cytoplasm of eukaryotic cells was subdivided into a variety of distinct compartments bounded by membrane barriers. As more types of cells were examined, it became apparent that these membranous compartments in the cytoplasm formed different organelles that could be identified in diverse cells from yeast to multicellular plants and animals.

DELEO.)  \n8  \n271  \ncytoplasm of a eukaryotic cell is occupied by membranous structures is illustrated in the electron micrograph of a maize root cell shown in Figure 8.1 . As we will see in the following pages, each of these organelles contains a particular complement of proteins and is specialized for particular types of activities. Thus, just as a house or restaurant is divided into specialized rooms where different activities can take place independent of one another, the cytoplasm of a cell is divided into specialized membranous compartments for analogous reasons. Keep in mind, as you examine the micrographs in this chapter, that these cytoplasmic organelles may appear as stable structures, like the rooms of a house or restaurant, but in fact they are dynamic compartments that are in continual flux.  \nIn the present chapter, we will examine the structure and functions of the endoplasmic reticulum, Golgi complex, endosomes, lysosomes, and vacuoles. Taken together, these organelles form an endomembrane system in which the individual components function as part of a coordinated unit.(Mitochondria and chloroplasts are not part of this interconnected system and were the subjects of Chapters 5 and 6. Current evidence suggests that peroxisomes, which were also discussed in Chapter 6, have a dual origin. The basic elements of the boundary membrane are thought to arise from the endoplasmic reticulum, but many of the membrane proteins and the soluble internal proteins are taken up from the cytosol, as described in Section 8.9.)  \nFigure 8.1 Membrane-bound compartments of the cytoplasm.
