Leucoplasts are a type of non-pigmented organelle found in plant cells, primarily involved in the storage of starches, oils, and proteins. They are a subtype of plastids, which include chloroplasts (involved in photosynthesis) and chromoplasts (involved in pigment synthesis). Leucoplasts are typically found in non-photosynthetic tissues, such as roots and tubers, where they play a crucial role in energy storage and metabolic processes. They can also differentiate into other types of plastids based on the plant's needs.
