The correct Answer is:
To answer the question "A green plant will turn yellow if placed in the dark. This is called," we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Phenomenon**: When a green plant is placed in the dark, it undergoes certain physiological changes. The lack of light affects its ability to produce chlorophyll, which is essential for photosynthesis and gives plants their green color. 2. **Identifying the Correct Term**: The condition where a plant turns yellow due to the absence of light is specifically referred to as "etiolation." This process involves the plant stretching towards any available light source and losing its green color as chlorophyll production decreases. 3. **Evaluating Other Options**: - **Phototropism**: This is the growth of a plant in response to light direction, not related to the yellowing of leaves. - **Dormancy**: This refers to a state where growth and development are temporarily halted, which is not the same as turning yellow due to lack of light. - **Chlorosis**: This is a condition characterized by yellowing of leaves due to insufficient chlorophyll, but it is not specifically caused by darkness. 4. **Conclusion**: Based on the definitions and the effects of darkness on a plant, the correct answer to the question is "etiolation." ### Final Answer: The correct term for a green plant turning yellow when placed in the dark is **etiolation**.
