Green bean inner bean pod parenchyma cells (Phaseolus vulgaris; Blue Lake variety), animated coloured scanning electron micrograph (SEM). Shown here is a fresh cut through the inner bean parenchyma cells. The cells are thin-walled and form a compact, succulent tissue with only small intercellular spaces. The inner parenchyma cells contain numerous starch granules. These parenchyma cells surround the bean seeds in the string bean pod.
