Every cell is encased in a protective layer referred to as the cell membrane. In plants, an additional barrier known as the cell wall offers further protection. All organelles found within cells are enclosed structures.
Cell membranes consist of a phospholipid bilayer featuring both extrinsic and intrinsic proteins. Studies of the plasma membrane structure revealed that the protein patterns of MITOCHONDRIA and CHLOROPLAST are most akin to that of the cell membrane.
<span>As the human population rises, the chances of a mass extinction event are also escalating.
Historically, an increase in human population correlates with the extinction of various species. The more the human population expands and the more habitats are destroyed to enhance living standards, the greater the risk of mass extinction becomes. </span>
