Answer:
If a plant's leaves only contained the vascular tissue xylem, then it will not be possible for the plant to absorb carbon dioxide. As carbon dioxide is required for photosynthesis to occur, this means that the process of photosynthesis will not take place.

=> Namely, 'Bb' should be.
This is the right shape :)
