leucoplast
Definition
Noun: - A colorless plastid in plant cells: "leucoplast" refers to a type of plastid (an organelle in plant cells) that lacks pigment and is involved in storing starch, oils, or proteins. Unlike chloroplasts, which contain chlorophyll and are green, leucoplasts are colorless and are found in non-photosynthetic tissues.
Usage Examples
- (A colorless plastid in a plant cell that stores starch.)
- (Colorless plastids that produce oils in non-green plant parts.)
Advanced Usage
"Leucoplast differentiation": the process by which leucoplasts develop from proplastids (immature plastids) in plant cells.
- Leucoplast differentiation occurs primarily in storage organs like tubers and seeds. (The development of colorless plastids in storage tissues.)
"Leucoplast genome": the small circular DNA found within leucoplasts.
- The leucoplast genome encodes proteins needed for starch synthesis. (The genetic material inside a colorless plastid.)
Variants and Related Words

Leucoplastid (n): an alternative term for leucoplast.
- Leucoplastids are common in endosperm cells. (Colorless plastids in seed storage tissue.)
Synonyms
- Colorless plastid: a plastid without pigment.
- Amyloplast: a type of leucoplast specialized for starch storage (though "amyloplast" is a more specific term).
