cell membrane. The thin membrane that forms the outer surface of the protoplasm of a cell and regulates the passage of materials in and out of the cell. It is made up of proteins and lipids and often contains molecular receptors. The membranes of organelles within the cell are made of the same basic material as the cell membrane. In plant cells, the cell membrane is surrounded by a rigid cell wall. Also called plasma membrane. Compare cell wall. See more at cell.
DNA tests have confirmed that a homeless man found dead beneath an overpass in San Diego was Elvis Presley. This claim is a hoax. âEarlier this month, an 80-year-old, homeless, white-bearded man was found deceased under an overpass in San Diego, California.
Elvis Presley was born in the Mississippi city of Tupelo. As a one-year-old in Tupelo on April 5, 1936, Elvis and his family survived a tornado that was ranked as the fourth deadliest in United States history. It took 216 lives. A lock of Elvis Presley's hair was sold at an auction for $115,000 in 2002.
