Why does mango have a big seed?

Mangoes have a large seed to protect the embryo of the plant. The seed contains the genetic material that will determine the characteristics of the new mango tree. The large size of the seed also helps to ensure that the embryo has sufficient nutrients to survive until it can establish itself in the soil.

Additionally, the large seed also provides structural support for the fruit. It helps to maintain the shape of the mango and provides a base for the attachment of the flesh. Additionally, the seed may provide buoyancy, facilitating dispersal of the fruit by water. The hard pit or stone encasing the seed protects it from being damaged by external sources like insects or microorganisms until germination conditions are right.
