Step-by-Step Solution
SA:V Ratio = Surface Area / Volume
Description of the Formula
Cell Volume (V): V = s³ (where s is the side length in µm)
Cell Surface Area (A): A = 6s²
Surface Area to Volume Ratio (SA:V): SA:V = A / V
This formula helps in understanding how cell size affects diffusion and metabolism. A higher SA:V ratio allows faster exchange of nutrients and waste.
Formula History
1665: Robert Hooke discovered and named the "cell" while examining cork.
19th Century: Scientists observed that smaller cells have a higher SA:V ratio, improving diffusion.
20th Century: Studies confirmed that cell size is limited by diffusion and metabolic efficiency.
