Umbilical hernia repair. Umbilical hernia repair is surgery to repair an umbilical hernia. An umbilical hernia is a sac (pouch) formed from the inner lining of your belly (abdominal cavity) that pushes through a hole in the abdominal wall at the belly button. You will probably receive general anesthesia (asleep and pain-free) for this surgery.
Give a plant too much sun and it will look bleached, pale, or event burned; too few hours and it will have thin leaves and elongated shoots. Some plants require about a half day of light, while others need up to 18 hours of light each day; the latter include vegetables, which will get pale without sufficient light.
In tropical forests where the trees keep their leaves all year round, some plants climb up the trunks and branches of the trees in order to reach the light. See image 1. There are even some plants that have leaves adapted to be able to carry out the process of photosynthesis with less sunlight than usual.
