Check out his original post <a title=\"Onion Root Tip Mitosis Lab\" href=\"https:\/\/www.kabt.org\/2008\/11\/08\/onion-root-tip-mitosis-lab\/\">here<\/a>. The thought occurred to me that the fixative should dissolve inter-cellular connections in leaf tissue the same as root tissue, so I gave a section of grocery store spinach tissue the same 6 minute warm fixative bath. The tissue flattened nicely (more or less), but I couldn&#8217;t see much in the way of cell definition. Sticking with the theme, I grabbed the aceto-orcein stain because it was already handy. Here&#8217;s what I saw:<\/p>\n<div id=\"attachment_4741\" style=\"width: 601px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.kabt.org\/wp-content\/uploads\/2014\/09\/photo-4.jpg\"><img decoding=\"async\" aria-describedby=\"caption-attachment-4741\" class=\"wp-image-4741 size-large\" src=\"https:\/\/www.kabt.org\/wp-content\/uploads\/2014\/09\/photo-4-1024x764.jpg\" alt=\"Spinach Cells - Aceto-orcein stain\" width=\"591\" height=\"440\" srcset=\"https:\/\/www.kabt.org\/wp-content\/uploads\/2014\/09\/photo-4-1024x764.jpg 1024w, https:\/\/www.kabt.org\/wp-content\/uploads\/2014\/09\/photo-4-300x224.jpg 300w, https:\/\/www.kabt.org\/wp-content\/uploads\/2014\/09\/photo-4.jpg 1920w\" sizes=\"(max-width: 591px) 100vw, 591px\" \/><\/a><p id=\"caption-attachment-4741\" class=\"wp-caption-text\">Spinach Cells &#8211; Aceto-orcein stain<\/p><\/div>\n<p>The remarkable definition in the organelle structure was surprising.
