Which plant tissue is responsible for the transport of sugar produced during photosynthesis?

• A. Epidermis
• B. Xylem
• C. Cortex
• D. Phloem

Answer: (D)

Verified step by step guidance

1. Step 1: Begin by understanding the function of each plant tissue mentioned in the problem. The epidermis is the outermost layer of cells that protects the plant and helps prevent water loss. The xylem is responsible for transporting water and minerals from the roots to the rest of the plant. The cortex is involved in storage and support. The phloem is responsible for transporting sugars and other organic compounds produced during photosynthesis.
2. Step 2: Recall the process of photosynthesis. During photosynthesis, plants produce glucose (a type of sugar) in their leaves. This sugar needs to be transported to other parts of the plant for energy and storage.
3. Step 3: Identify the tissue specialized for sugar transport. The phloem is the vascular tissue that transports sugars, amino acids, and other organic molecules from the leaves (source) to other parts of the plant (sink). This process is known as translocation.
4. Step 4: Compare the functions of the listed tissues to determine which one matches the role of sugar transport. The epidermis, xylem, and cortex do not perform this function, leaving the phloem as the correct answer.
5. Step 5: Conclude that the phloem is the plant tissue responsible for transporting sugar produced during photosynthesis, as it is specifically adapted for this role.
