What role does phloem play in plant biology?

• A. Transports water
• B. Stores seeds
• C. Transports the products of photosynthesis
• D. Absorbs nutrients from soil

Answer: (C)

Phloem is a critical component of a plant's vascular system, specifically responsible for transporting the products of photosynthesis, such as sugars, from the leaves where they are produced to various parts of the plant, including roots, stems, and fruits. This transportation occurs through a process known as translocation. The significance of this function lies in ensuring that energy, in the form of glucose, is distributed throughout the plant for growth, development, and storage. Unlike other functions such as water transport, which is primarily the role of xylem, or nutrient absorption from the soil, which involves roots, the primary and defining role of phloem is focused on the movement of organic compounds produced during photosynthesis. This makes it essential for overall plant health and efficiency, as it allows for effective energy use and storage, critically impacting a plant's ability to thrive.
