Methods of fixing, embedding and sectioning of Amoeba proteus for electron microscopy are described. The fine structure of the various organelles: nucleus, mitochondria, food vacuoles; and the contractile vacuole, is discussed in detail. A number of minor unidentified objects has also been found. The functional implications of the structural findings are considered.

The effects of panchromatic illumination at 0.8, 6.7, 122, 436, and 835 W/m2 on the contractile vacuole of Amoeba proteus were measured. At a level as low as 122 W/m2, a gradual deterioration of vacuolar performance is noted: extended cycles, slow or partial systole, plateaux, inhibition of coalescence, etc. Pseudosystole, observed for the first time, supports our hypothesis that osmotic losses oppose vacuolar growth.
