Abstract 

The relationship among leaf size, leaf protoplast (cell) size, chloroplast size, and chloroplast number were investigated in tobacco and Arabidopsis thaliana at various developmental stages. In tobacco, protoplasts, less than 15.6 μm in diameter had less than 20 chloroplasts, 0.93 μm in thickness and 3.3 μm in length on average. As protoplast size increased from 30 μm to 45 μm in diameter, chloroplast size remained the same (1.57 μm in diameter and 5.55 μm in length on average), but chloroplast number increase from 42 to 101 on average. A similar relationship was also observed in A. thaliana. The ratio of total chloroplast volume to protoplast volume was constant (0.105 in tobacco and 0.325 in A. thaliana) over various developmental stages.
