Question 15 0.5 pts What is the primary reason that mammalian red blood cells are used in the study of the plasma membrane? • There are a lot of them and they are easily obtained. • They contain larger plasma membranes than any other cell type. • They are of particular interest because they are made up of a lipid monolayer. • They lack nuclei and membrane-bounded organelles.

3. Blood cells (3 pts) Vertebrates (animals with skeletons) are all eukaryotes and have blood that contains red blood cells carrying hemoglobin. Here we will use non-human blood but treat the material as a biohazard and follow all procedures as directed. View the prepared blood smear slide under 40X, 100X, and 400X magnification. The cells will appear pink to red and may be faint in color. Find and draw a few red blood cells (these are pinkish-red in color). Mature red blood cells do not contain a nucleus and are easily characterized by their toroid (doughnut) shape. What is the function of red blood cells and how is it possible that they function without a nucleus? Under 40X magnification, find a white blood cell (nucleus is amorphous and stained purple). Draw and label the nucleus and note its unusual shape.

Look at the four cell images below. The magnification for all images is 400x Cheek cells, darker blue rods are bacteria Smooth muscle cells, separated Red blood cells Sperm cells Using the microscope images above as a guide, sketch one of each cell type. Label the plasma membrane. Label the cytoplasm. Only the cheek cell has a visible nucleus. Label the nucleus in this cell. Mature red blood cells do not have a nucleus. The nucleus of smooth muscles and sperm cells is difficult to see in these micrographs. In humans, only sperm cells have a flagellum. Label the flagellum. 9. The cheek cells are classified as epithelial cells. The function of these cheek cells is to line the oral cavity. Compared to the shape of red blood cells, how does the shape of cheek cells differ? Why is the shape of the cheek cells well-suited to their function? 10. The function of all muscle cells is to contract. What is the meaning of contract in the context of a muscle cell? How does the shape of a smooth muscle cell change when it contracts? Compared to the structure of cheek cells, why is the structure of a smooth muscle cell well-suited to its function? 11. The function of sperm cells is to "swim" to an egg cell. How does the structure of these cells suggest their function? 12. Red blood cells, also known as erythrocytes, travel in the fluid stream of blood through tubes called arteries, capillaries or veins. How does the structure of these cells suggest that they are well-suited to travel through tubes?
