These structures include the plasma (cell) membrane, which regulates the entrance and exiting of materials into and out of the cell; the nucleus, which contains the genetic material; and the cytoplasm, which contains the organelles.
The cell images in this blood cell atlas were photographed by an MC-80 Automated Digital Cell Morphology Analyzer on peripheral blood smears prepared by an SC-120 Slide Maker & Stainer following a standard Romanovsky staining procedure.
Fig. 1.1 Diagram of a tube of anticoagulated blood that has been allowed to sediment, showing the separation of blood into red cells, a buffy coat (white cells and platelets) and plasma.
• Cell description: Plasma cells have a bluish cytoplasm with an eccentric nucleus and a characteristic halo around the nucleus as shown in the image. • Features: Plasma cells are the terminally differentiated B cells.
In labs on blood cells, you’d normally be looking at blood smears using a microscope. In this set of labs, you’ll examine 3D models of blood cells suspended in plasma. To make it possible for you to view the cells in 3D, we’ve created these models to look like drops of blood before they’re smeared.
o Examples of membranous organelles are the plasma membrane, nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. o Examples of non-membranous organelles are ribosomes , cytoskeleton , and centrosomes .
• What’s the shortest-living cell? The white blood cells that hunt down Speed • How fast do organelles move? When pulled along by the cytoskeleton, they cover about 5 micrometres per second. • What is the fastest cell? A cell such as a white blood cell, which uses its internal cytoskeleton to crawl along, can
