Which term describes the process of moving nutrients from leaves to other parts of the plant?

• A. Translocation
• B. Photosynthesis
• C. Transpiration
• D. Respiration

Answer: (A)

Translocation is the movement of nutrients, especially sugars produced in the leaves, through the phloem from source tissues to sink tissues such as roots, developing shoots, and fruits. This is the system-wide distribution that delivers energy-rich compounds to parts of the plant that need them. Photosynthesis is the process that makes sugars using light, carbon dioxide, and water. Transpiration is the loss of water from the plant via stomata, which helps drive water movement in the xylem but doesn’t move nutrients to other parts. Respiration is the cellular breakdown of sugars to release energy, not their transport. So the term that best describes moving nutrients from leaves to other parts is translocation.
