WebCells that secrete many proteins—such as salivary gland cells that secrete digestive enzymes, or cells of the immune system that secrete antibodies—have many Golgi stacks. In plant cells, the Golgi apparatus also makes polysaccharides (long-chain carbohydrates), some of which are incorporated into the cell wall. WebThe plasma membrane—the outer boundary of the cell—is the bag, and the cytoplasm is the goo. Of course, a cell is ever so much more than just a bag of goo.

WebUnlike prokaryotic cells, eukaryotic cells have: 1) a membrane-bound nucleus; 2) numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi … WebVesicles and Vacuoles. Vesicles and vacuoles are membrane-bound sacs that function in storage and transport. Vacuoles are somewhat larger than vesicles, and the membrane of a vacuole does not fuse with the membranes of other cellular components. Vesicles can fuse with other membranes within the cell system ( Figure 5.11. 1 ).
WebPEROXISOME – the organelle behind the film ‘Lorenzo’s Oil’ Peroxisomes are small rounded organelles found free floating in the cell cytoplasm. These structures contain at least 50 enzymes and are separated from the cytoplasm by a lipid bilayer single membrane barrier. They are called peroxisomes because they all produce hydrogen peroxide.
WebThe 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.
