The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding the Question**: The question asks for the term that describes the bulk movement of substances in plants. 2. **Identifying the Options**: The options given are translocation, cyclosis, active transport, and diffusion. 3. **Defining Each Term**: - **Translocation**: This is the process of transporting nutrients (especially sugars) from the source (where they are produced) to the sink (where they are used or stored). - **Cyclosis**: This refers to the movement of cytoplasm within a cell, also known as cytoplasmic streaming. - **Active Transport**: This is the movement of substances against their concentration gradient, requiring energy. - **Diffusion**: This is the passive movement of molecules from an area of higher concentration to an area of lower concentration. 4. **Analyzing the Process**: The bulk movement of substances, particularly sugars in plants, occurs through the phloem via translocation. This process involves the movement from the source (like leaves) to the sink (like roots). 5. **Conclusion**: Based on the definitions and the context of the question, the bulk movement of substances in plants is best described as **translocation**. **Final Answer**: The bulk movement of substances in plants is also called **translocation**. ---
