Movement of minerals and chemical compounds with a plant occurs during

Step 1: Analyze the question The question asks which process moves minerals and chemical compounds within a plant. The key idea is transport inside the plant body, covering both minerals and organic compounds such as sugars.

Step 2: Review each option

• A. Osmosis: The movement of water from a region of high water potential to one of low water potential across a semi-permeable membrane. It moves water only, not minerals or compounds in general.
• B. Translocation: The movement of dissolved substances through the plant's vascular tissues. In the phloem it carries manufactured food (sucrose, amino acids), and the term is also used for the transport of mineral salts in the xylem. This matches the question.
• C. Transpiration: The loss of water vapour from leaves through the stomata. It creates the pull that draws water up the plant, but it is water loss, not the movement of compounds.
• D. Diffusion: The movement of particles from high to low concentration. It happens over short distances, such as gas exchange in leaves and the uptake of some ions. It does not explain long-distance transport through the plant.

Step 3: Conclusion Translocation is the process responsible for moving minerals and chemical compounds around the plant.

Answer: B. Translocation

Exam tip: Remember it this way: Translocation = Transport of Things (solutes). Transpiration = Tears of water lost from leaves. When a question says "minerals and compounds" moving within the plant, think translocation.
