DENDROLOGY

Detailed explanation-1: -The fluid-filled interior area of the chloroplasts that encircle the grana and thylakoids is known as the stroma. It contains chloroplast DNA, starch, and ribosomes, as well as Calvin cycle enzymes. Ans. The stroma contains grana, which are stacks of thylakoids.

Detailed explanation-2: -A jellylike matrix called the stroma surrounds the thylakoids and grana. The most noticeable characteristic of chloroplasts is their green color. This is due to two types of the pigment chlorophyll, which is concentrated in the grana.

Detailed explanation-3: -Grana are heaps of film bound, leveled discoid sacs called thylakoids that contain chlorophyll atoms. They are the chloroplasts’ essential practical units. . The homogeneous framework where grana are inserted is known as stroma. The granum is the site of light response, while the stroma is the site of dull response.
