The correct answer is Leucoplast.Concept:Plastids are present only in plant cells. Plastids are differentiated into three different types on the basis of the colour, i.e., type of pigment found in them.Leucoplasts ChromoplastChloroplastExplanation:LeucoplastLeucoplast are the colorless plastids of varied shapes and sizes with stored nutrients in the form of carbohydrates, lipids, and proteins.These are as follows:Amyloplasts: are the carbohydrate-containing leucoplasts that store starch, e.g., tuber of potato, grain of rice, and wheat.Elaioplasts: are the leucoplasts that store oils and fats, e.g., rose.Aleuroplasts: They are protein storing leucoplasts, e.g., castor endosperm.Thus, leucoplast stores starch, oil and protein granules.Additional InformationChloroplast:These are photosynthetic plastids, which are green in colour and found in the leaves of all green plants.They have lamellae organized in the form of grana.They contain mainly chlorophylls and some amount of carotene and xanthophyll. Chromoplast: These are non-photosynthetic coloured plastids which synthesize and store carotenoid pigments.They appear orange, red, or yellow in colour.Xanthoplast:Xanthoplasts have yellow pigments i.e. xanthophylls, carotenoids.
