The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding Bulk Movement in Plants**: The question asks about the bulk movement of substances in plants. This refers to the way in which nutrients, water, and other substances are transported throughout the plant. 2. **Identifying the Options**: We have four options to consider: - Option 1: Translocation - Option 2: Cyclosis - Option 3: Active transport - Option 4: Diffusion 3. **Analyzing Each Option**: - **Translocation**: This is the process by which organic substances (mainly sugars) are transported from the leaves (source) to other parts of the plant (sinks) such as roots and fruits. - **Cyclosis**: This refers to the movement of cytoplasm within a cell, not the bulk movement of substances in the plant as a whole. - **Active Transport**: This is a cellular process that requires energy to move substances against their concentration gradient, but it does not specifically refer to the bulk movement of substances throughout the plant. - **Diffusion**: This is the passive movement of substances from an area of higher concentration to an area of lower concentration, but it does not encompass the bulk movement of substances. 4. **Conclusion**: Given the definitions and functions of each term, the correct answer is **Translocation**. This term specifically refers to the bulk movement of food substances in plants. **Final Answer**: The bulk movement of substances in plants is also called **Translocation**. ---

Which of the following statements is/are incorrect? (i) Water and minerals, and food are generally moved by a mass or bulk flow system. (ii) Bulk flow can be achieved either through a positive hydrostatic pressure gradient or a negative hydrostatic pressure gradient. (iii) The bulk movement of substances through the conducting tissues of plants is called translocation.

Which of the following is true/false regarding transport of substances in plants ? (i) Mass flow is the movement of substances in bulk as a result of pressure difference (ii) Bulk flow is achieved only through a positive hydrostatic pressure gradient (iii) The apoplast system is the system of interconnected protoplasts (iv) Most of the water flow in the roots occurs via the apoplast since the cortical cells are loosely packed, and offer no resistance to water movement.
