A stroma is the connective, part of a cell, organ or tissue. The  function of a stroma is to hold the cell, organ, or tissue together  and help it maintain form. Edit.
The stroma is the connective tissue and the associated blood vessels and nerves which pass through it. The stroma supports the parenchyma, which in turn consists of those epithelial, muscle, or nerve cells which carry out the specific function(s) of the organ and which usually comprise the bulk of the organ.
