Does cell size matter?

Yes. As cells (or any 3-dimensional objects for that matter) grow, their surface areas and volumes also get larger. As the sizes get bigger, the volume increases much faster than the surface area (I'll include why at the end). read more

As a closing activity for this lesson, students will answer the simple question, "When it comes to cells, does size matter." Hopefully, after modeling cell size and analyzing the surface area to volume ratio, students will conclude that the smaller the cell the more efficient the surface area to volume ratio. read more

Background: The approach to anemia is traditionally based on the Mean Cell Volume. Based on this approach anemia is subdivided into microcytic, normocytic and macrocytic causes. read more
