Options

A. Symptoms due to lesser water absorption in plants
B. Symptoms due to poor photosynthesis in plants
C. Deficiency symptoms of mineral nutrients
D. Symptoms due to excess water absorption in plants.

Answer

### Step-by-Step Solution:

1. **Understanding Hunger Signs in Plants**:
- Hunger signs in plants refer to symptoms that indicate a deficiency of essential nutrients necessary for their growth and development.

2. **Types of Nutrients**:
- Nutrients are categorized into two main types:
- **Macronutrients**: These are required in larger quantities (e.g., nitrogen, phosphorus, potassium).
- **Micronutrients**: These are required in smaller quantities (e.g., iron, manganese, zinc).

3. **Examples of Hunger Signs**:
- **Phosphorus Deficiency**: One common hunger sign is the appearance of red or purple coloring in young plants, which indicates a deficiency of phosphorus.
- **Potassium Deficiency**: Another example is the drying up of leaves, which suggests that the plant is lacking potassium.

4. **Distinguishing Hunger Signs from Other Symptoms**:
- It is important to differentiate hunger signs from other symptoms caused by factors such as:
- Lesser water absorption (not a hunger sign).
- Poor photosynthesis (not a hunger sign).
- Excess water absorption (not a hunger sign).
- The correct identification of hunger signs is crucial for proper plant care and nutrition.

5. **Conclusion**:
- Hunger signs are specific symptoms that indicate a deficiency of mineral nutrients in plants, and recognizing these signs is essential for maintaining plant health.
