Selected cell organelles were investigated at a high level of resolution with the transmission electron microscope, using ultrathin serial sections to create three-dimensional reconstructions. On the basis of these reconstructions, morphological data of chloroplast fine structures, mitochondria, and peroxisomes from control and drought-stressed spinach leaves were evaluated and compared. Mesophyll cell chloroplasts of control plants contained 60% stroma, 23% thylakoids, and 16% starch. In drought-stressed plants, the volume of both the stroma and the thylakoids increased to 68% and 32%, respectively. The amount of plastoglobuli was about 0.3% in both samples. Chloroplasts of stressed plants differed from control plants not only in the thylakoid and stroma values but also in the lack of starch grains. Mitochondria occurred in variable forms in control and stressed samples. In stressed plants, mitochondria had only 65% of the volume compared with control plants. Peroxisomes were inconspicuous.
