Which tissue system is primarily responsible for transporting nutrients in a tree?

• A. Xylem
• B. Phloem
• C. Parenchyma
• D. Colenchyma

Answer: (B)

The primary tissue system responsible for transporting nutrients in a tree is the phloem. This tissue specifically transports the products of photosynthesis, primarily sugars, from the leaves where they are produced to other parts of the tree where they are needed for growth, energy, or storage. Phloem is part of the vascular system in plants and operates in a bidirectional flow, meaning it can transport nutrients both upwards and downwards in the plant. This flexibility is crucial for maintaining the tree's health, especially during periods of growth when energy and nutrients are needed in various locations within the tree structure. In contrast, xylem is responsible for transporting water and minerals from the roots to the upper parts of the plant, serving a different but equally essential function. Parenchyma and colenchyma are types of ground tissue found in plants, primarily involved in storage and support, but they do not play a direct role in nutrient transport like the phloem does. Understanding the specific roles of these tissue systems helps clarify how a tree functions both in nutrient delivery and overall growth.
