The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Phloem**: - Phloem is a type of vascular tissue in plants responsible for transporting nutrients, particularly organic compounds like sugars. 2. **Direction of Transport**: - The primary function of phloem is to translocate food from the leaves (where it is produced through photosynthesis) to other parts of the plant, including roots and growing tissues. 3. **Source and Sink Concept**: - In the context of phloem transport, the leaves act as the 'source' (where food is produced), and the roots serve as the 'sink' (where food is utilized or stored). 4. **Types of Solutes Transported**: - Phloem primarily transports organic solutes (like sucrose) and some inorganic nutrients. The sugars are often converted from glucose to sucrose for efficient transport. 5. **Correct Option Identification**: - The question asks where phloem translocates solutes. The correct answer is that phloem translocates a variety of organic and inorganic solutes mainly from the leaves to other parts of the plant. 6. **Elimination of Incorrect Options**: - The other options (from roots to leaves, roots to aerial parts, and roots to phloem) are incorrect because they suggest a direction of transport that does not align with the primary function of phloem. ### Final Answer: The phloem translocates a variety of organic and inorganic solutes mainly **from the leaves to the other parts of the plant**. ---
