Factors needed for germination

1. Water –activates hormones and enzymes seed swelling and bursting of seed coat

2. Oxygen- many metabolic reactions needed for aerobic respiration; no metabolic activities? no germination

3. Suitable temperature- enzyme activity requires optimum temperatures

Reflection:

• Which plants survived best in our lab?
