The answer is the second one (or B): stomata.

Explanation for each option:

  • Stroma: This is the fluid-filled space inside the chloroplasts where the Calvin cycle of photosynthesis takes place. It is not involved in the direct intake of carbon dioxide from the atmosphere.
  • Stomata: These are small openings on the surface of leaves and stems that allow for gas exchange. They open to let in carbon dioxide, which is necessary for photosynthesis, and release oxygen.
  • Mesophyll: This refers to the inner tissue of a leaf, containing many chloroplasts. While it is the site where photosynthesis occurs, it is not the structure that opens to let in carbon dioxide.

Summary: Plants must open their stomata to let in the carbon dioxide that is required for photosynthesis.

Compare these two structures. O=C=N: O=C=N Determine whether the two represent resonance contributors of a single species or depict different substances. If two structures are not resonance explain why. Select the single best answer. The two structures are resonance contributors of the same species. The two structures are not resonance contributors because they contain bond orders having integer values. The two structures are not resonance contributors because they contain different numbers of electrons. The two structures are not resonance contributors because they have different arrangements of atoms. The two structures are not resonance contributors because they contain different bond orders. The two structures are not resonance contributors because each structure is present in its most stable (lowest energy) configuration.
