Dispersal of Seeds:
Dispersal of seeds is the process by which seeds are scattered away from the parent plant to ensure the survival and growth of the plant species. It helps in reducing competition among the plants for sunlight, water, and nutrients. One of the main methods of seed dispersal is through natural processes.
Methods of Seed Dispersal:
- Wind: Some plants have seeds that are lightweight and have wings or hairs that help them be carried away by the wind to new locations.
- Water: Seeds of some plants are able to float on water and are carried to new locations by rivers, streams, or oceans.
- Animals: Some seeds have hooks, spines, or burrs that attach to the fur of animals and are transported to new areas. Other seeds are eaten by animals and are excreted in a different location.
- Explosive Action: Some plants have seedpods that explode when they are ripe, scattering the seeds in all directions.
- Gravity: Some seeds simply fall to the ground and are dispersed by gravity, rolling away from the parent plant.
Importance of Seed Dispersal:
Seed dispersal is crucial for the survival and reproduction of plant species. It helps in colonizing new habitats, avoiding competition with parent plants, and increasing genetic diversity within a population. Without seed dispersal, plants would struggle to establish themselves in new environments and adapt to changing conditions.
In conclusion, seed dispersal is a vital process that ensures the continued growth and survival of plant species. By scattering seeds away from the parent plant, plants are able to thrive in diverse environments and contribute to the overall biodiversity of ecosystems.
Process of scattering of seeds away from the parent plant:a)Germinatio...
Process of scattering of seeds away from the parent plant:
1. Germination:
- Germination is the process by which a seed grows into a new plant.
- It begins when the seed absorbs water and the embryo inside the seed starts to grow.
- The root emerges first, followed by the shoot, which grows towards the sunlight.
2. Dispersal:
- Dispersal is the process of scattering seeds away from the parent plant to new locations.
- This is important for the survival and growth of plant species as it helps in reducing competition for resources.
- There are various mechanisms of seed dispersal, including wind, water, animals, and self-dispersal.
3. Protection:
- Plants have evolved different strategies to protect their seeds during dispersal.
- Some plants produce fruits that are attractive to animals, which eat the fruit and then disperse the seeds through their droppings.
- Other plants have seeds that are adapted for wind dispersal, such as having wings or being lightweight.
4. Agriculture:
- Agriculture is the practice of cultivating plants for food, fiber, medicinal plants, and other products.
- While agriculture involves the intentional planting of seeds, it is not part of the natural process of seed dispersal away from the parent plant.
5. None of these:
- This option is incorrect as seed dispersal is a natural process that is essential for the survival and diversity of plant species.
