Given below is a figure of the internal structure of an organelle found in plants cells. Study the figure and answer the following questions :

(i) Identify the organelle and name the physiological process that occurs in this organelle.

(ii) Label the guidelines 1 and 3 of the figure.

(iii) Write a well balanced equation for the above metabolic process.

(i) The given organelle is Chloroplast. Photosynthesis occurs in this organelle.

(ii) The labelled guidelines are:

• 1 → Stroma
• 2 → Thylokoid
• 3 → Granum

(iii) Balanced chemical equation representing the process of photosynthesis is given below:

$6\text{CO}$2 + 12\text{H}2\text{O} \xrightarrow[\text{chlorophyll}]{\text{light energy}} \text{C}6\text{H}{12}\text{O}6 + 6\text{H}2\text{O} + 6\text{O}_2 \uparrow
