Which of the following cell organelles is only found in plant cells?

Plastids are unique organelles found solely in plants. Plants are autotrophic and exhibit photosynthesis due to the presence of green-colored plastids known as chloroplasts. Leucoplasts, which are colourless plastids, store food resources such as starch, proteins, and lipids, but chromoplasts, which are non-green plastids, are crucial for pollination and fruit dissemination.
