Figure 3From: The effect of experimental warming on leaf functional traits, leaf structure and leaf biochemistry in Arabidopsis thalianaTransmission electron micrographs showing leaf chloroplast and mitochondrial ultrastructure of Arabidopsis grown at three temperatures. Samples were taken at ambient temperature (A and D), elevated temperature I (B, E and F), and elevated temperature II (C). Note that there were larger starch grains in the chloroplasts of A. thaliana leaves grown at ambient temperature than at elevated temperatures I and II. In addition, there were more mitochondria nearby chloroplasts at elevated temperatures I and II than at ambient temperature. St, starch grain; Mi, mitochondrion; Ch, chloroplast. Bar, 1 μm (A-F).Back to article page
