Question

Refer to the given diagrammatic of an electron micrograph of a section of chloroplast.
Select the option which correctly depicts the function of parts X, Y and Z.

• A. X-Dark reaction ; Y-Light reaction ; Z-Cytoplasmic inheritance
  
• B. X-Light reaction ; Y-Carbohydrate synthesis ; Z-Carbohydrate storage
  
• C. X-Light reaction ; Y-Carbohydrate storage ;Z-Carbohydrate synthesis.
• D. X-Carbohydrate synthesis; Y- Carbohydrate storage ; Z- Cytoplasmic inheritance
  

Answer 1

The correct option is B X-Light reaction ; Y-Carbohydrate synthesis ; Z-Carbohydrate storage

Light reaction (or photochemical phase) of photosynthesis mainly occur on the grana thylakoids. Dark reaction (or biosynthetic phase) which involve the synthesis of carbohydrates by $C{O}_2$ fixation occur in the stroma (or matrix) of chloroplasts. The chloroplast matrix of higher plants stores starches temporarily in the form of starch granules.

So the correct option is B.
