Amyloplasts store carbohydrates, aleuroplasts store proteins & the elaioplasts stores fats. These are the types of ____ .

These are found only in plant cells and in certain protists (e.g. Euglena). They are of two main types - chromoplasts and leucoplasts. The chromoplasts contain coloured pigment and occur in the cells exposed to sunlight. The leucoplasts are colourless and occur in the cells not exposed to light. They act as storage organelles and are classified on the basis of the material stored in them. Amyloplasts store carbohydrates while the aleuroplasts store proteins. The fat-storing leucoplasts are termed as elaioplasts.
