1. Most cells are very small. What physical and metabolic contraints limit cell size?
2. What problems would an enormous cell encounter?
3. What adaptions might help a very large cell to survive?

One of the main reasons cells are small is due to the surface area/volume constraint. Consider a ball. As it expands, its surface area expands at a slower rate than its volume. (You can check out the mathematics of that by looking at the volume of a sphere versus the surface area of a sphere.) In other words, as it expands its surface area/volume ratio gets smaller and smaller. Therefore, to have the largest surface area/volume ratio, the cells should be as small as ...
Cell size is justified.
Mycoplasma Variable Surface Antigen (VSA)
1.What is VSA and how does it under go size and phase variation?
2.How does VSA variation affect and is effected by the host immune response?
3.How does VSA variation affect growth and nutrition? What are the benefits and liabilities of the different forms of VSA?
4.What are the roles of VSA forms in biofilms formation and how is that hypothisizse to affect the immune response?
