Seed Dispersal Activity | PDF - Free Printable

Task: Analyze the seed dispersal methods for each plant and identify the adaptations that help in their dispersal.

#### 1. Broom
- Seed Dispersal Method: Wind
- Adaptation: The seeds of broom plants are lightweight and have feathery structures, which allow them to be easily carried by the wind. This adaptation helps in spreading the seeds over a wide area.

#### 2. Blackberry
- Seed Dispersal Method: Animals
- Adaptation: Blackberries produce fleshy, sweet fruits that attract animals such as birds and mammals. When these animals eat the fruit, the seeds pass through their digestive systems and are deposited elsewhere, often far from the parent plant. This method ensures widespread dispersal.

#### 3. Pea
- Seed Dispersal Method: Explosion
- Adaptation: Pea pods have a mechanism where they dry out and split open suddenly, ejecting the seeds with force. This explosive action helps disperse the seeds away from the parent plant, increasing their chances of finding suitable growing conditions.

#### 4. Pond Iris
- Seed Dispersal Method: Water
- Adaptation: Pond iris grows near water bodies, and its seeds are adapted to float on water. This allows the seeds to be carried by water currents to new locations, ensuring dispersal across different areas.

#### 5. Burdock
- Seed Dispersal Method: Animals
- Adaptation: Burdock seeds have hooked bristles (called "awns") that attach to the fur or feathers of animals. As animals move around, they carry the seeds to new locations, aiding in dispersal.

#### 6. Dandelion
- Seed Dispersal Method: Wind
- Adaptation: Dandelion seeds are equipped with fine, hair-like structures called pappus. These structures act like tiny parachutes, allowing the seeds to be carried long distances by the wind. This adaptation is highly effective for widespread dispersal.

Summary of Answers:

| Plant | Seed Dispersal Method | Adaptation |
|-------------|-----------------------|---------------------------------------------------------------------------|
| Broom | Wind | Lightweight seeds with feathery structures for wind dispersal. |
| Blackberry | Animals | Fleshy, sweet fruits that attract animals for seed dispersal. |
| Pea | Explosion | Pods that dry out and split open explosively to eject seeds. |
| Pond Iris | Water | Seeds that can float on water for dispersal. |
| Burdock | Animals | Hooked bristles (awns) that attach to animals for seed dispersal. |
| Dandelion | Wind | Fine, hair-like pappus structures that catch the wind for dispersal. |
