31. It involves the use of special computed tomography scanning techniques to assess the lung parenchyma . 32. Succulent plants such as the cacti store water in the vacuoles of large parenchyma tissues. 33. The pathological hallmark of cirrhosis is the development of scar tissue that replaces normal parenchyma . 34. Microscopically, the lesions are not true cysts, but communicate with the surrounding parenchyma . 35. They feed singly, eating the lower epidermis and parenchyma , leaving the upper epidermis. 36. This leads to a somewhat inflated mine in which most of the parenchyma is consumed. 37. The larva feeds on the palisade parenchyma . 38. In later mines the leaf blade becomes rather inflated and the parenchyma nearly all consumed. 39. Paratracheal parenchyma is sparse, as incomplete narrow borders, not clearly visible with hand lens. 40. In his earlier studies, he worked mostly in the fields of plant anatomy and parenchyma .
