Seed Dispersal worksheet - Free Printable

Problem Description:

The task is to categorize the seeds shown in the image into the correct seed dispersal methods. The categories provided are:

1. Eaten by Animals
2. Catching a Lift
3. Wind
4. Water
5. Exploding

Solution Approach:

To solve this problem, we need to understand how each seed is dispersed naturally. Here’s a breakdown of the dispersal methods and which seeds fit into each category:

#### 1. Eaten by Animals
- Seeds that are dispersed by animals (e.g., birds, mammals) often have fleshy fruits or are enclosed in structures that attract animals.
- Examples: Apple, berries, acorn.

#### 2. Catching a Lift
- Seeds that hitch a ride on animals or objects, such as burrs or hooks that attach to fur or clothing.
- Examples: Burdock.

#### 3. Wind
- Seeds that are lightweight and can be carried by the wind.
- Examples: Dandelion, sycamore.

#### 4. Water
- Seeds that float on water or are adapted to travel through water.
- Examples: Coconut.

#### 5. Exploding
- Seeds that are dispersed by explosive mechanisms, where the fruit bursts open to release the seeds.
- Examples: Peas, Himalayan balsam.

Step-by-Step Categorization:

#### Eaten by Animals
- Apple: Fleshy fruit eaten by animals.
- Berries: Fleshy fruit eaten by animals.
- Acorn: Eaten by animals like squirrels.

#### Catching a Lift
- Burdock: Seeds have hooks that attach to animal fur or clothing.

#### Wind
- Dandelion: Lightweight seeds with parachutes for wind dispersal.
- Sycamore: Winged seeds designed for wind dispersal.

#### Water
- Coconut: Buoyant and can float on water.

#### Exploding
- Peas: Pods burst open to disperse seeds.
- Himalayan Balsam: Pods explode when ripe to scatter seeds.

Final Answer:

Here is the categorization of the seeds:

- Eaten by Animals: Apple, berries, acorn
- Catching a Lift: Burdock
- Wind: Dandelion, sycamore
- Water: Coconut
- Exploding: Peas, Himalayan balsam

Boxed Final Answer:

\[
