Seeds that disperse by water
-----------------------------
Water is an important medium for seed dispersal in many plants. It helps in the movement of seeds from one place to another, allowing them to reach new habitats and grow in different areas. Among the given options, the seed that disperses by water is the Lotus.
The Lotus plant is a freshwater plant that is well-known for its beautiful flowers and large, round leaves. It grows in shallow water bodies such as ponds, lakes, and marshes. The seeds of the Lotus plant have adaptations that enable them to disperse through water.
Adaptations of Lotus seeds for water dispersal
-----------------------------------------------
1. Buoyancy: Lotus seeds have air spaces in them, which make them float on water. This allows them to be carried away by water currents to new locations.
2. Water-resistant coating: The outer layer of the Lotus seed is covered with a tough, water-resistant coating. This helps to protect the seed from getting waterlogged and allows it to remain buoyant on the water's surface.
3. Hooks and spines: Lotus seeds have small hooks and spines on their surface, which help them to attach to the feathers of water birds or the fur of animals that come into contact with them. This allows the seeds to be transported over long distances.
4. Long dormancy period: Lotus seeds have a long dormancy period, which means they can remain viable for a long time even when submerged in water. This allows them to survive in water bodies until the conditions are favorable for germination.
Importance of water dispersal in Lotus seeds
--------------------------------------------
Water dispersal is crucial for the survival and distribution of Lotus seeds. It allows the seeds to colonize new areas, ensuring the continued growth and survival of the plant species. It also helps to increase genetic diversity by allowing the seeds to mix with other populations of Lotus plants.
In conclusion, the Lotus seeds disperse by water due to their adaptations for water dispersal, such as buoyancy, water-resistant coating, hooks and spines, and a long dormancy period. This mode of dispersal ensures the seeds' ability to reach new habitats and contribute to the growth and survival of the Lotus plant species.

Lotus seeds are dispersed by water because the lotus plant grows in water.
