Question

Carotenes and chlorophyll pigment types can be traced in

• A. Matrix
• B. Lamellae
• C. Stroma
• D. Grana

Answer 1

The correct option is D Grana

Internally, the chloroplast has two main components; the thylakoid lamellae and stroma. The stroma contains enzymes of the calvin cycle and carries out the dark reaction. The light reaction is carried out by thylakoid lamellae arranged as grana. Carotenes and chlorophyll pigments are present in the grana. These pigments are involved in capturing light energy for the light reaction. The inner space of mitochondria is filled with mitochondrial matrix.

So, the correct answer is option D.
