Question

the structures of the dermal and vascular systems work together to transport and provide materials essential for photosynthesis. which statement correctly identifies how they work together? the xylem transports glucose to the roots for storage, and the phloem allows oxygen to enter the leaf. the phloem transports water for transpiration, and the stomata allows oxygen to enter the leaf. the xylem transports water from the roots, and the stomata allows carbon dioxide to enter the leaf. the stomata transports glucose from the roots, and the phloem allows carbon dioxide to enter the leaf.

Explanation:

To solve this, we analyze the roles of xylem, phloem, and stomata in plant systems:

• Xylem transports water (and minerals) from roots to leaves (for photosynthesis).
• Phloem transports glucose (product of photosynthesis) to other parts.
• Stomata are pores that allow gas exchange (CO₂ in, O₂ out) and water vapor loss (transpiration).

Now, check each option:

• Option 1: Xylem doesn't transport glucose (phloem does), and phloem doesn't let O₂ in (stomata do). Incorrect.
• Option 2: Phloem doesn't transport water (xylem does), and stomata let CO₂ in (not O₂ for photosynthesis input). Incorrect.
• Option 3: Xylem transports water from roots to leaves. Stomata open to let CO₂ (needed for photosynthesis) enter the leaf. This matches their functions. Correct.
• Option 4: Stomata don't transport glucose (phloem does), and phloem doesn't let CO₂ in (stomata do). Incorrect.

Answer:

The third option (The xylem transports water from the roots, and the stomata allows carbon dioxide to enter the leaf.)
