Nothing harmful to you.
Swallowing a clementine seed is generally not harmful. The seed will likely pass through your digestive system without any issues. However, in rare cases, it could potentially cause an obstruction or discomfort, so it's best to avoid swallowing them whenever possible.
No nothing will happen.
There is nothing wrong with eating an apple seed. If you were to swallow it, nothing would happen to you. It would just come out in a matter of hours like everything else. Did you know that seeds concealed in fruit are designed TO BE EATEN? When animals come along, they eat the fruit and swallow the seeds whole. The animal makes the perfect mode of transportation for a seed.
The seed would stop growing.
it would grow at a faster rate then a normal seed
I was told nothing would happen because you have acid in your stomach so it will probably melt. But im not totally sure about it.
the seed would wither and die
No, a seed will not grow inside you if you swallow it. Your stomach acid will break down the seed, preventing it from germinating and growing. It will pass through your digestive system harmlessly.
i swallowed a popcorn seed and nothing happened
No.. lol
Yes, it will not harm you.
