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.
Sowing the Seeds. Staghorn sumac seeds are ready for sowing after the cold treatment. Fill a pot with moist seed-starting mix up to 1/2 inch from the top. Tamp down the soil and evenly spread the seeds over the soil. Sprinkle a 1/8-inch layer of seed-starting mix over the seeds.
