W.O.D: Cotyledon – “seed leaf;” the first leaf/leaves to germinate from a seed.

Warm-Up Question: Did your plant have one or two cotyledons?

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.

How are flowers different?• Monocots have petal in multiples of 3.

• Dicots have petals in multiples of 4 or 5.

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:

• Were most of our plants planted for the garden monocots or dicots?
