Fig. 3.1-8. Transverse section of the funiculus (the stalk that attaches a seed to a fruit as it develops) in bean (Phaseolus vulgaris). These parenchyma cells have contents that have been stained red, making the intercellular spaces quite visible. The cytoplasmic staining is so intense it is difficult to see nuclei, but in many cells the very dark red, small dot is a nucleolus (arrows), and the nucleus can be detected in some of the cells as a mass with slightly different color surrounding the nucleolus.
