Question

Plastids present in unilluminated cells are

• A. Chloroplast
• B. Chormoplast
• C. Leucoplast
• D. Proplastid

Answer 1

The correct option is C Leucoplast

A. Chlorophylls are chlorophyll-containing plastids. These are green coloured.

B. Chromoplasts are the coloured plastids (other than green colour).

C. Leucoplasts are the colourless plastids.

D. Proplastids are the cell organelles in plants, which develop into plastids.

Hence, plastids present in unilluminated cells are leucoplasts because they are colourless.

So, the correct answer is 'Leucoplast'.
