Pleural Cavity is the body cavity that surrounds the right and left lung. The pleura is a serous membrane which folds back to form a two-layered, membrane structure. The thin â¦ space between the two pleural layers is known as the pleural cavity; it normally contains a small amount of pleural fluid. The outer pleura parietal pleura is attached to the chest wall.
Germinating the Seeds. To germinate staghorn sumac seeds place them in a warm room away from direct sunlight. Regularly mist the soil in the pot with a spray bottle to keep it moist. After germination, remove the plastic wrap and position the pot in a sunny window so the seedlings can grow.
For example, European primrose (Primula vulgaris) seeds normally take 2 to 4 weeks to germinate if the conditions are right, but may germinate more quickly (in 2 or 3 days) if placed in a small pot of damp compost and placed in a polythene bag indoors at 15 - 20 degrees C.
