FAQs on Dispersal of Seeds Video Lecture - Science Class 5

1. How do seeds disperse?
Ans. Seeds disperse through various methods such as wind, water, animals, and self-dispersal mechanisms like exploding pods or seeds that are propelled away from the plant.
2. Why is seed dispersal important?
Ans. Seed dispersal is essential for the survival and reproduction of plant species as it helps in colonizing new areas, reducing competition among plants, and increasing genetic diversity within populations.
3. What are the benefits of wind dispersal for seeds?
Ans. Wind dispersal allows seeds to travel long distances, reach new habitats, and avoid competition with parent plants, enhancing the chances of successful germination and growth.
4. How do animals help in seed dispersal?
Ans. Animals assist in seed dispersal by eating fruits and then excreting the seeds in a different location, burying seeds underground for future use, or carrying seeds on their fur or feathers to new areas.
5. What are some examples of self-dispersal mechanisms in plants?
Ans. Some examples of self-dispersal mechanisms in plants include exploding pods in plants like touch-me-nots, seeds that are propelled by water in aquatic plants, or seeds that have hooks or spines to attach to passing animals for dispersal.
