Answer 1

Answer: (A)

HSK pathway plants have the ability to photosynthesis even in water stress condition. These plants have excellent affinity to prevent photorespiration in when the concentration of carbon dioxide is very less. These plants have dimorphic chloroplast Granal chloroplast present in spongy mesophyll cell where initial carbon dioxide fixation takes place. Agranal chloroplast present in bundle sheath cell where glucose is formed.
