Why do some fruits have many whereas some have one seed?

Answer»

Hi,,,
OVULES in the ovary become seeds when the ovary is DEVELOPING into a fruit.
So since some PLANTS like  mango are uniovulate (have one ovule) , the have one seed. Some fruits like papaya, watermelon have many ovules and hence after the ovary matures into a fruit, the ovules will turn into seeds and hence the fruits will have many seeds.

CONCLUSION ; It all depends on the number of ovules in the ovary. If there is one ovule , there will be one seed. If there is more than one ovule, there will be more than one seed in the fruit.
Thank u
