  Write the name of different plant parts in which chromo last, chloroplast and leucoplast are present.

Answer:

  Plastids occur in most plant cells, but are absent in animal cells. Like mitochondria, plastids also have their own genome (i.e., DNA) and ribosomes. They are self-replicating organelles like the mitochondria, i.e., they have the power to divide. Plastids are of following three types 1. Chromoplasts Coloured plastids (except green colour). They add colour to organs  e.g., flowers fruits, for attracting animals to perform pollination and fruit dispersal. 2. Chloroplasts Green-coloured plastids. These are the sites of photosynthesis and are present in the leaves of the plant. 3. Leucoplasts The colourless plastids. Leucoplasts takes part in storage of food and can be present anywhere in an organism.
