Identifying tissue G in vascular bundle

Steps:

• Vascular bundles in stems contain xylem and phloem for transport.
• Xylem conducts water and minerals upward from roots to leaves.
• Phloem transports sugars and nutrients from leaves to roots or growing areas.
• Without the photograph, tissue G cannot be specifically identified as xylem or phloem.

Why D is correct:

• Not enough information to confirm; D incorrectly states xylem's role, as xylem transports water, not sugars.

Why the others are wrong:

• A: Phloem transports sugars bidirectionally, not exclusively to roots.
• B: Phloem does not transport water; that's xylem's function.
• C: Xylem does transport water to leaves, but G's identity is unconfirmed.

Final answer: Not enough information.
