Answer #1

Answer. D. Similar in structure to the plasma membrane of the cell.

Cells are basic unit and functional structure of life which are composed of carbon, hydrogen, oxygen and nitrogen. All oraganisms are made up of one or more cells and new cells are generated by self-replication. Cells contain organelles which include mitochondria, endoplasmis reticulum, golgi bodies, lysosome. Each organelles perform specific function. Like plasma membrane, oraganelles membranes function to keep the inside 'in' and the outside "out". This membrane allows chemical reaction and synthesis product to be kept separate from one another by compartmentalizing there reactions and this compartments are surrounded by lipid layers.
