• Chloroplasts were isolated from leaves of four plant species (spinach, New Zealand spinach, Swiss Chard and tomato) and their osmotic behaviour was compared. Maximal contraction of chloroplasts from all plant sources occurred at 0.3-0.4 M Sucrose. The volume of the particles at this sucrose concentration was also similar in all cases; 300 mm^3 per 10^<10> chloroplasts. At higher and lower sucrose concentrations, the chloroplasts swell. The degree of swelling, especially in higher sucrose concentrations, differed in chloroplasts from different sources. Tomato chloroplasts are most sensitive, and the spinach chloroplasts are the most resistant to all types of treatment. Tomato chloroplasts require rather high phosphate concentrations for good preservation. Changes in optical density at 520 mμ can be used to get a rough idea about the condition of the particles.
