Most parenchyma cells retain the ability to divide and differentiate into other types of plant cells under particular conditions—during wound repair, 

for example, It is even possible to grow an entire plant from a single parenchyma cell.

The surfaces of the cells that form the alveoli (small air spaces of the lung) are coated with surfactant, which decreases the alveolar surface tension. 

Lung surfactant contains 80 to 90% phospholipid by weight, and 70 to 80% of the phospholipid is phosphatidylcholine, mostly the dipalmitoyl species.
