RecapThere are two types of Vascular Plants that produce Seeds:
Angiosperms & Gymnosperms Angiosperm seeds develop within a flower.
Angiosperms can be divided into two groups called MonocotsMonocots and DicotsDicots
Gymnosperm seeds develop without a sealedcontainer; called “naked seeds.”

Check on your seeds!! What stage are they in?

From a Seed to a Seedling
• The development of a seed into a seedling is called GERMINATION.GERMINATION.
• What enables a seed to germinate?
* Seed coat damage* Seed coat damage
* Exposure to temperature changes* Exposure to temperature changes
* Penetration of * Penetration of HH22OO & & OO22 through the seed through the seed

Importance of CotyledonsImportance of Cotyledons• “Cots”- provide foodfood for the embryo.
• Once the food is used up, the cotyledons shrivel up and fall off.

Fruit and Seed Dispersal
• Three common ways fruit and seeds are dispersed:– Wind– Animals (bees, butterflies, birds, bats)
– Water

Fruit ClassificationFruit Classification
• A fruitfruit is a mature ovary.
• Fruits can be classified using these two two characteristicscharacteristics:– How many flowers or pistils form the fruit?– Is the fruit dry or fleshy?

Flowers of Monocots & Dicots
Objectives:
Today in lab, students will be able to:
1. Identify the parts of a flower.
2. Identify monocots and dicots based on type of flower and/or type of seed.
3. Properly label a flower diagram and seed diagram.

• Pollen- contains sperm for fertilization.
• Pistil (Carpel)-female part of the flower which includes the stigma, style and ovary; it produces ovules, which are similar to eggs in animals. Produces seeds and fruit.
• Stigma- collects pollen on its surface and aids in fertilization
• Style- elevates the stigma to collect pollen
• Ovary- produce ovules (eggs); when fertilized ovules become seeds and fruits.

Confusing Flowers
• Flowers with spurred petals. Count them. There are five. This is a dicot, and the netted venation of the leaves will bear this out. The plant is a colombine, Aquilegia canadensis, and the number of spur this time is always five.
