Science: Seed dispersal questions | Worksheet | PrimaryLeap.co.uk - Free Printable

Problem Analysis:

The task involves understanding the concept of seed dispersal and answering questions based on the provided information. Seed dispersal is the process by which seeds are spread away from the parent plant to ensure their survival and growth in new locations. The text explains different methods of seed dispersal, including:

1. Animals: Seeds can be transported by animals eating them or sticking to their fur.
2. Wind: Seeds can float away in the wind.
3. Explosion: Some plants launch their seeds explosively.
4. Water: Seeds can float on water to reach new locations.

Questions and Solutions:

#### Question 1: Which of the following best describes seed dispersal?
- Option a: A seed growing into a young plant
- This describes germination, not dispersal.
- Option b: The scattering or spreading of seeds to different places
- This accurately describes seed dispersal.
- Option c: A plant starting to make its own food
- This describes photosynthesis, not dispersal.

Correct Answer: b. The scattering or spreading of seeds to different places

#### Question 2: Which seeds use the wind to travel from the parent plant?
- Option a: Coconuts
- Coconuts are dispersed by water, not wind.
- Option b: Apple seeds
- Apple seeds are typically dispersed by animals (e.g., birds or mammals).
- Option c: Dandelion seeds
- Dandelion seeds have feathery structures that allow them to float in the wind.

Correct Answer: c. Dandelion seeds

#### Question 3: Seeds can be dispersed by animals.
- The text explicitly states that seeds can be dispersed by animals eating them or sticking to their fur. For example, some seeds hitch rides inside animals like birds, while others stick to the fur of mammals.

Correct Answer: True

#### Question 4: Which of the following helps disperse coconuts?
- Option a: Wind
- Coconuts are not typically dispersed by wind.
- Option b: Water
- Coconuts are buoyant and can float on water to reach new locations.
- Option c: Animals
- While animals may play a minor role, the primary method of coconut dispersal is water.

Correct Answer: b. Water

#### Question 5: What will happen if all seeds of a plant fall under the parent plant?
- The text explains that if all seeds fall under the parent plant, many would die due to lack of space, air, water, sunlight, and minerals. Plants cannot move around like humans and animals, so dispersal is essential for their survival.

Correct Answer: b. Many will die

Final Answers:

1. b. The scattering or spreading of seeds to different places
2. c. Dandelion seeds
3. True
4. b. Water
5. b. Many will die
