Key Insights

  • 🌱 The process of seed dispersal ensures the proper routing of seeds in the soil, leading to the growth of new plants.
  • 💦 Seeds can be dispersed by wind, water, explosion, and animals.
  • 💨 Dispersal by wind occurs when lightweight seeds are carried away by the wind to distant places.
  • 🌊 Dispersal by water allows fruits that float to be carried across seas and oceans.
  • 🤗 Explosion dispersal happens when fruits or pods burst open, throwing the seeds at a distance.
  • 🌱 Animals play a crucial role in seed dispersal by consuming fruits and either excreting the seeds or releasing them while moving.
  • 🌱 Seed dispersal is necessary to prevent plants from competing with each other for resources.

in our previous video we learnt a fertilization process and what it leads to the process helps in the formation of fruits and seeds enclosed in them the seeds are the structures containing the embryo within now all that's required is proper routing of the seeds in the soil this will result in germination and does growth of a new plant but not the q...

Questions & Answers

Q: How do seeds get dispersed by wind?

Seeds of plants like dandelions have structures that are lightweight and easily carried by the wind, allowing them to be dispersed to distant places.

Q: How are seeds dispersed by water?

Fruits that float, such as those of the Lotus and coconut palm, are carried by water. Coconuts, for example, can travel for thousands of kilometers across seas and oceans.

Q: What is dispersal by explosion?

In some cases, fruits or pods containing seeds burst open suddenly, throwing the seeds with considerable force. Plants like broom and pea belong to this category.

Q: How do animals help in seed dispersal?

Animals play a role in seed dispersal by consuming fruits and then excreting the seeds in a different area. The seeds may also be dropped while the animal is moving, helping plants grow in new locations.

Summary & Key Takeaways

  • Fertilization leads to the formation of fruits and seeds.

  • Seed dispersal is the process of transferring seeds to various places.

  • Seeds can be dispersed by wind, water, explosion, and animals.
