Which of the following best describes the role of phloem in the transport system of plants?

• A. Providing structural support to the plant
• B. Facilitating gas exchange in leaves
• C. Transport of sugars and nutrients from leaves to other parts of the plant
• D. Transport of water and minerals from roots to leaves

Answer: (C)

Verified step by step guidance

1. Understand the function of phloem in plants: Phloem is a type of vascular tissue responsible for transporting organic nutrients, particularly sugars, throughout the plant.
2. Recognize the source of these nutrients: Sugars are primarily produced in the leaves through the process of photosynthesis.
3. Identify the direction of transport: Phloem transports these sugars from the leaves to other parts of the plant, including stems, roots, and fruits.
4. Differentiate phloem from xylem: While phloem transports sugars and nutrients, xylem is responsible for transporting water and minerals from the roots to the leaves.
5. Conclude the role of phloem: The primary role of phloem is the transport of sugars and nutrients from the leaves to other parts of the plant, supporting growth and development.
