Plastids are species specific and are found in all plant cells and in euglenoides. They bear some specific pigments thus imparting specific colours to the part of the plant which posseses them. Based on the type of pigments, Plastids are classified into three types. They are Leucoplasts, Chromoplasts, Chloroplasts.
Leucoplasts : They are the colourless plastids which store food materials. Based on the storage product, they are of 3 types namely Amyloplasts (store starch), elaioplasts (store oils) and aleuroplasts (store proteins).
Chromoplasts : They are coloured pigments which were in yellow, orange or red in colour. In these plastids, fat soluble carotenoids like carotene and xanthophylls are present which imparts orange, red or yellow colour.
Chlorgplasts : These are green coloured plastids which help in synthesis of food materials by photosynthesis. They contain chlorophyll and carotenoid pigments which trap light energy. Each chloroplast is a oval or spherical, double membrane bound cell organelle. The space present inner to inner membrane is called stroma. A number of organised flattened membranas sacs called thylakoids are present in the stroma. Thylakoids are arranged in stacks like the piles of coins called grana. The thylakoids of the different grana are connected by membranous tubules called the stroma lamellae. The stroma of the chloroplast contains enzymes required for the syntheis of carbohydrates and proteins.
