23 palisade tissue: 13 spongy tissue Chloroplasts/cell
||Poplar Populus sp.
||Ivanova LA, Ronzhina DA, Ivanov LA, Stroukova LV, Peuke AD, Rennenberg H. Chloroplast parameters differ in wild type and transgenic poplars overexpressing gsh1 in the cytosol. Plant Biol (Stuttg). 2009 Jul11(4):625-30. p.628 fig.2DPubMed ID19538400
||For counting chloroplasts, leaf pieces were macerated
in a solution containing 5% CrO3 and 1 N HCl and
the number of chloroplast per cell was counted under a
light microscope in cell suspensions in 30 replicates for
both palisade and spongy tissue.
