Question

Write the names of those plant parts that contain colourless plastids, chloroplasts, other coloured plastids.

Accepted Answer

Plastid is a generic name for divergent plant organelles, such as chloroplasts in green leaves, etioplasts in dark-grown seedlings and amyloplasts in storage cells of cereal grains. Compared to some of the other plastids, gerontoplasts are formed during senescence.

Generally, leucoplasts are colourless plastids that are commonly found in colourless leaves and rapidly growing tissues (tubers, stems, roots etc). Here, leucoplasts serve as the site of starch formation and storage.

Chloroplasts are semiautonomous organelles which possess their genome and gene expression system. Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth.

Chromoplasts are brightly coloured plastids that act as the site of pigment accumulation. They are typically found in the fleshy fruits, flowers as well as various other pigmented parts of the plant such as leaves.
