Suitable environmental conditions for seed germination are

Options

A. adequate moisture light anaerobic conditions
B. adequare moisture low temperaturee light
C. adequate moisture suitable temperature and oxygen
D. light water absence oxygen

Answer

**Step-by-Step Solution:**

1. **Identify the Key Requirements for Seed Germination:**
- Seeds require specific environmental conditions to germinate effectively. The primary factors include moisture, temperature, light, and oxygen.

2. **Moisture:**
- Adequate moisture is crucial for seed germination. Water activates enzymes that start the metabolic processes necessary for growth.

3. **Temperature:**
- Seeds require a suitable temperature range for germination. This range varies among different species but is generally above freezing and below extreme heat.

4. **Oxygen:**
- Oxygen is essential for cellular respiration, which provides the energy needed for the seed to grow. Seeds cannot germinate in anaerobic (absence of oxygen) conditions.

5. **Light:**
- While not all seeds require light to germinate, some do. Light can be a factor in the germination process for certain species.

6. **Evaluate the Options:**
- Review the provided options based on the identified requirements.
- **Option 1:** Adequate moisture, light, and aerobic conditions - This is partially correct but lacks mention of temperature.
- **Option 2:** Adequate moisture, low temperature, light - Incorrect as seeds generally need suitable, not low, temperatures.
- **Option 3:** Adequate moisture, suitable temperature, and oxygen - This option meets all the necessary conditions for germination.
- **Option 4:** Light, water, absence of oxygen - Incorrect as oxygen is required for germination.

7. **Conclusion:**
- The correct answer is **Option 3: Adequate moisture, suitable temperature, and oxygen**.
