WHAT IS PLASTIDS

  •     Plastids are cells that store specific things.
  •     They are large cytoplasmic organelles found in the cells of most plants, but they are not found not in animal cells..
  •     Plastids form small colorless bodies called proplastids.
  •     Once formed certain kinds of plastids can be converted into other types.
    For ex. chlorophyll can be synthesized with a leucoplast and light.
    There are three plastid categories- Leucoplasts (white or colorless plastids that store starch granules) , Chromoplasts (colored plastids that store pigment molecules) and Chloroplasts which are essential in the photosynthetic process.
