Question

Chloroplasts without grana are found in

• A. Bundle sheath cells of $C_3$ plants
• B. Bundle sheath cells of $C_4$ plants
• C. Mesophyll cells of all plants
• D. Mesophyll cells of $C_4$ plants

Answer 1

The correct option is B Bundle sheath cells of $C_4$ plants

Agranal chloroplasts are the characteristic feature of C4C4 plants. The agranal chloroplasts were found to be located in bundle sheath cells. The C4C4 plants often possess characteristic leaf anatomy called kranz anatomy. Their vascular bundles are surrounded by two rings of cells; the inner ring, called bundle sheath cells, contains starch-rich chloroplasts lacking grana, which differ from those in mesophyll cells present as the outer ring.

So, the correct option is 'Option B'.
