Question

Distinguish between :
Leucoplast and chromoplast

Answer 1

Leucoplast	Chromoplast
They are colourless plastids.	They are orange-red plastids.
They usually occur in unexposed parts of plants.	They are commonly found in exposed parts like flowers and fruits.
Internal lamellae are present.	Internal lamellae degenerate.
They take part in storage of various substances like starch (amyloplasts), fat (elaioplasts) and protein (aleuroplasts).	Chromoplasts are rich in carotenoid and lipids.
The shape is more regular, mostly rounded.	The shape is irregular and having angles due to crystallisation of pigments.
They can change to other types of plastids.	They do not get changed to other types.
Leucoplasts do not attract animals as they are colourless.	Being coloured, chromoplasts attract animals for pollination and fruit dispersal.
