Grade 5 task 3 worksheet - Free Printable

Problem Analysis:

The task involves categorizing images of seeds and fruits based on their dispersal methods: Wind, Water, Animals, and Explosion. Additionally, there is a multiple-choice question about features unlikely to be found in fruits dispersed by water.

Step-by-Step Solution:

#### Part 1: Categorizing Images Based on Dispersal Methods

We need to match each image with the appropriate dispersal method. Let's analyze each image:

1. Top Row:
- Image 1 (Berries/Fruits): These fruits are typically dispersed by animals (e.g., birds or mammals) that eat them and later excrete the seeds.
- Dispersal Method: Animals
- Image 2 (Lotus Seeds): Lotus seeds have a buoyant structure and are adapted to float on water.
- Dispersal Method: Water
- Image 3 (Small Seeds with Fine Hair): These seeds have fine hair-like structures that help them be carried by wind.
- Dispersal Method: Wind
- Image 4 (Plant Growing in Water): This indicates dispersal by water, as the plant is growing in an aquatic environment.
- Dispersal Method: Water

2. Bottom Row:
- Image 5 (Flowers/Plants with Explosive Seed Pods): Some plants, like impatiens, disperse seeds through explosive mechanisms when the seed pod bursts open.
- Dispersal Method: Explosion
- Image 6 (Seed with Wings): Seeds with wings (e.g., maple seeds) are adapted for dispersal by wind.
- Dispersal Method: Wind
- Image 7 (Mimosa Plant): Mimosa plants can disperse seeds explosively when the seed pods burst open.
- Dispersal Method: Explosion
- Image 8 (Fleshy Fruit): Fleshy fruits are often eaten by animals, which then disperse the seeds.
- Dispersal Method: Animals

#### Final Matching:
- Wind: Image 3 (Fine hair), Image 6 (Seed with wings)
- Water: Image 2 (Lotus seeds), Image 4 (Plant growing in water)
- Animals: Image 1 (Berries/Fruits), Image 8 (Fleshy fruit)
- Explosion: Image 5 (Explosive seed pods), Image 7 (Mimosa plant)

#### Part 2: Multiple-Choice Question

The question asks which feature is unlikely in fruits dispersed by water. Let’s analyze the options:

- a. Fine hair: Fine hair can help lightweight fruits float on water, so this is likely.
- b. Fibrous covering: A fibrous covering can provide buoyancy and protection, making it likely for water-dispersed fruits.
- c. Lighter fruit: Lighter fruits are more likely to float on water, so this is also likely.
- d. Spongy outer: A spongy outer layer would make the fruit sink rather than float, making it unlikely for water dispersal.

#### Correct Answer:
- d. Spongy outer

Final Answers:

1. Categorization of Images:
- Wind: Image 3, Image 6
- Water: Image 2, Image 4
- Animals: Image 1, Image 8
- Explosion: Image 5, Image 7

2. Multiple-Choice Question:
- d. Spongy outer

Boxed Final Answer:

\[
\boxed{
\text{1. Wind: Image 3, Image 6; Water: Image 2, Image 4; Animals: Image 1, Image 8; Explosion: Image 5, Image 7}
}
\]
\[
\boxed{d}
\]
