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

Answer: (A)

Movement of nutrients or other materials within a plant is translocation. In vascular plants, this refers to the phloem carrying sugars and other organic solutes from sources (like mature leaves) to sinks (such as roots, developing shoots, or fruits) where they’re needed. This transport can go in different directions depending on where the sources and sinks are. It’s different from transpiration, which is the loss of water from leaves that helps pull water up the xylem; photosynthesis, which is the process of converting light energy into chemical energy to make sugars; and respiration, which breaks down sugars to release energy.
