How Seeds Get Spread Worksheet - Free Printable

Problem Overview:

The task is to match each seed with the method by which it might be dispersed. Seed dispersal is the process by which plants spread their seeds to new locations, ensuring that new plants have room to grow and can colonize different areas.

Key Concepts:

1. Seed Dispersal Methods:
- Animals: Seeds can be dispersed by animals that eat them (e.g., berries) or carry them (e.g., acorns).
- Water: Seeds can float on water and be carried to new locations.
- Wind: Lightweight seeds can be blown by the wind.
- Gravity: Heavy seeds may fall from the plant due to gravity.
- Other Mechanisms: Some seeds have specific adaptations for dispersal (e.g., dandelion seeds have parachutes).

2. Seeds and Their Characteristics:
- Berry: Typically eaten by animals and dispersed through their droppings.
- Maple seed (Samara): Has wings and is adapted for wind dispersal.
- Acorn: Often carried by animals like squirrels and stored underground.
- Persimmon: A fruit that animals eat and disperse through their droppings.
- Lotus: Seeds are often dispersed by water as they can float.
- Dandelion: Seeds have feathery structures that allow them to be carried by the wind.

Solution:

We will match each seed with the most appropriate dispersal method based on its characteristics.

#### 1. Raccoon
- Match: Berry
- Explanation: Raccoons are omnivores that eat berries. After consuming the berries, the seeds pass through their digestive system and are deposited in new locations.

#### 2. Squirrel
- Match: Acorn
- Explanation: Squirrels are known for collecting and burying acorns. This behavior helps disperse the acorns to new locations where they can germinate.

#### 3. Water
- Match: Lotus
- Explanation: Lotus seeds are buoyant and can float on water. They are often dispersed by water currents to new locations.

#### 4. Wind
- Match: Maple seed (Samara)
- Explanation: Maple seeds have wing-like structures that allow them to glide through the air when blown by the wind.

#### 5. Gravity
- Match: Persimmon
- Explanation: Persimmon fruits fall from the tree due to gravity. Animals may then consume the fallen fruit and disperse the seeds.

#### 6. Bear
- Match: Dandelion
- Explanation: While bears do not directly disperse dandelion seeds, dandelions are primarily wind-dispersed. However, if we consider the context of animal interaction, bears might inadvertently help disperse seeds by moving through areas where dandelions grow.

Final Matches:

1. Raccoon → Berry
2. Squirrel → Acorn
3. Water → Lotus
4. Wind → Maple seed
5. Gravity → Persimmon
6. Bear → Dandelion
