Why does mango seeds don't dissolve in water?

Mango seeds do not dissolve in water due to their tough, fibrous structure and composition. They are primarily made up of hard seed coat materials, including cellulose and lignin, which are resistant to water and do not break down easily. Additionally, the seed's internal components, such as starch and proteins, are bound in a way that prevents them from dissolving in water. This durability helps protect the embryo inside, allowing it to survive until conditions are favorable for germination.
