Question

Plastids contain

• A. Double membrane covering
• B. DNA, RNA and ribosomes
• C. Lamellae
• D. All of the above

Answer 1

The correct option is D All of the above

• Plastids are a pigment containing double membrane-bound organelle which is the site of manufacture and storage of chemical compounds.
  
• Plastids are descended from a bacterial cell and thus, it possesses its own DNA, RNA and ribosomes (similar to abacterial cell).
• Each granum within a chloroplast consists of a disc-shaped membranous sac called lamellae or thylakoids.
• The grana are intercon­nected by a network of tubules called stroma lamellae.
• So, the correct answer is 'All of the above'.
