Answer
Ability to multiply by a fission-like process
Explanation
Solution
Plastids are small bodies found free in most plant cells. These are found absent in fungi, certain bacteria, algae and multicellular animals. The plastids can be categorized to : Chromoplasts : Coloured (other than green) plastids. Chloroplasts : Green coloured plastids : Leucoplasts : Colourless plastids. All these three are double membrane bound structures which are mainly used for trapping radiation and storage purposes. New plastids arise from proplastids by a fission like process.
