An electron micrograph of a plant cell shows two different types of plastids. One of them is known to store oils and fats in them; such a plastid is known as:

Step-by-step solution

Based on the type of pigments plastids can be classified into chloroplasts, chromoplasts and leucoplasts. The leucoplasts are the colourless plastids of varied shapes and sizes with stored nutrients: Amyloplasts store carbohydrates (starch), e.g., potato; elaioplasts store oils and fats whereas the aleuroplasts store proteins.
