Value 
1
µm/sec
Range: equivalent to ~3 hours to fall 1 cm µm/sec

Organism 
Budding yeast Saccharomyces cerevisiae 
Reference 
Calculation analogous to the one given in "Random walks in biology" Howard Berg, Princeton University Press, 1993 pp.62 
Method 
uses the equation v=mg/6*pi*eta*R, where v is the terminal velocity, eta is the viscosity, m is the effective mass after subtracting the effect of bouyancy by subtracting the volume * density of water. 
Comments 
Assumes the cell is a sphere of radius 2 micron and density 1.1 (BNID 103876). Viscosity of water 0.001 Pascal*Sec. Please comment if you know of experimental values in the literature
