Reproduction in Plants
Describe the various ways by which seeds are dispersed.
Seeds and fruits of plants are carried away by the wind, water, and animals. They are called dispersal agents.
1. Dispersal by Wind - Seeds and fruits which are small in size and lightweight are dispersed by wind. They have hair or wings-like structure which help them to fly in the air. Ex: Sunflower, drumstick, and maple.
2. Dispersal by Water - Some seeds and fruits are dispersed by water. These seeds have the floating ability in the form of spongy or fibrous outer coats. Ex: Coconut and Water lily.
3. Dispersal by Animals - Some seeds develop hooks on their surface by which they get attached to the hairy bodies of animals and carried away to distant places. Ex: Xanthium and Urena.
4. Dispersal by Explosion - Some seeds are dispersed by the bursting of fruits with sudden jerks. In this, the seeds are scattered far away from the parent plant. This is called the explosive mechanism of seed dispersal.Ex: Pea, caster and balsam

What our students and parents say about us!
Saiyam is using EduSaksham online courses from past one year. He is able to complete his tutorials, worksheets, and assignments on his own. Once he is done with worksheets, he can check his answers and if he has done any mistakes, then he can check the correct answers and explanations. They have been given so well that he is able to understand them himself and rarely he asks us for any clarification. He enjoys using the platform and has learned and improved a lot in Mathematics. I would recommend EduSaksham to all parents who want their kids to learn in a structured way and also enjoy the learning process.
Neeraj (Saiyam's Father)
I would like to thank Edusaksham on behalf of my son Aditya who attended " Math Olympiad crash course for 5 weeks". As per Aditya, this course helped him to understand new topics like Roman numerals and decimal places which were not taught in his school till date and had a better understanding of other topics. I personally thank EduSaksham for all the help and support.
Geeta Bansal (Aditya's Mother)
We had a good experience with EduSaksham. Because sheets are available online, Vedant enjoyed doing more and more sheets without any reminders. I could leave him on his own as he was very much motivated to cover the topics. Practice is very important in maths but it becomes difficult for us to prepare sheets, I am glad we found EduSaksham where in a lot of in a lot of sheets are available for practice and the quality of questions are also good. As it's a venture from IITians we could think of giving it a try and I am glad we tried
Shikha Chowdhary (Vedant's Mother)
I have grown up in a family where my father used to give me practice maths paper every day which I need to finish before I go to play. I think that strong foundation of solving new questions every day helped me to clear my IITJEE exam. But as working women, I always had time challenge to create practice Math papers for my daughter. Thanks to EduSaksham, their questions are so logical and conceptual that I don't feel the guilt of not creating practice questions by myself :). There are plenty of worksheet along with the tutorials for each chapter. It has made parents life easier :) And the best part is my daughter loves doing it. Thank you EduSaksham.
