Quantification of growth patterns with overlays provides information on the growth rates and habit. Root growth patterns of plants 8.5 days old from the ground control (A) and flight experiment (B) were quantified with mapping options in Adobe Illustrator CS3. Numerical values were assigned to both the absolute distance grown and the degree of deviation from the vertical (C) which creates an overlay of data containing information on the growth rates and habit (detail in D).
