Why is the surface area of a cell so important in determining maximum cell size? a. a very large cell needs very little surface area relative to its volume b. a very small cell can't exchange material across its surface c. a very large cell would need to exchange a very large amount of material with the external environment  d. a typical cell has more surface area than volume e. all of the above

Model 1 and Model two are diagrams showing the process of two types of bulk transport which require energy. Which of the following statements correctly describes the type of transport that is occurring in Model 1 and Model 2? A . Model 1 and 2 are types of passive transport. B . Model 1 and 2 help to transport only one molecule at time. C . Model 1 shows endocytosis, where the cell surrounds molecules from outside the cell and takes the molecules into the cell. D . Model 2 shows endocytosis, where the cell surrounds molecules from inside the cell and releases them outside of the cell.

What of the following would cause a cell to shrink? A. Increased activity of the sodium-potassium pump B. Increased heart rate OC. Increased water absorption by the kidneys OD. Increased Intracellular osmolarity S BURDEN

18.. Use the following diagram to answer the questions. Assume the membrane is semipermeable to glucose, water, and iodine (IKI). A. Which solutes will diffuse into the cell? B. Which solute will diffuse out of the cell? 10% glucose 40% glucose C. Which solute will not diffuse at all? 20% starch 0% starch D. What type of solution (the outside of the cell - hypertonic, isotonic or hypotonic) does the diagram represent? 70% water 50% water 10% IKI E. What color will the cell be at the conclusion of this experiment? What color will the solution in the beaker be? Justify your answer,

Which of the following provides the most likely explanation for the limiting factor of a cell's size? A B с D As the cell size increases, its volume increases while its surface area does not. As the cell size increases, its volume increases at a faster rate than its surface area. As the cell size increases, its volume increases at a slower rate than its surface area. As the cell size increases, its surface area increases while its volume does not.

Cells in a hypertonic solution tend to: a. shrink due to water loss b. swell due to water gain c. stay the same size due to water moving into and out of the cell at the same rate d. none of the above
