Compare the stroma and thylakoid in relation to their location in the chloroplast.

The stroma is the watery part found in the inner membrane, which contains circular DNA molecules, RNA, ribosomes, lipids, granules of starch, among other substances. The chloroplast genetic process and photosynthesis reactions take place in the stroma. Thylakoids are flattened sacs, or vesicles, that form part of the inner membrane structure of the chloroplast to initiate the light-dependent photosynthesis reaction.

Explanation:

Chloroplasts are typical and exclusive organelles of plant cells that possess chlorophyll. It also has a double membrane (external and internal) and between them an intermembrane space. The inside is filled with a gel called a stroma. The stroma surrounds the thylakoid and grana within the chloroplast. It presents a DNA independent of the nucleus and plastoribosomes. Immersed in the stroma, there are flattened sacs called thylakoids or lamellae, the interior of which is called lumen. Thylakoids can spread throughout the stroma or stack in bundles called grana. Enzyme systems are located in the membrane of grana or thylakoids that capture energy from the sun and carry out the transport of electrons to form ATP.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
