W.O.D: Monocot – “one seed leaf;” fibrous roots, parallel veins, and flowers with 3x petals.
. Warm-Up Question: Name a common monocot.
How are cotyledons different between monocots and dicots?
What is an angiosperm?
• Angiosperms are flowering plants
How are roots different?
• Monocot roots are fibrous.• Dicot roots are taproots.
How are leaves different?
• Monocots have parallel veins in their leaves.
• Dicots have net-like veins in their leaves.

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?
