eli5-How do seeds work???? I was just eating an apple and for some reason the unappreciated potential of the apple seeds struck me.
In: Biology
Fruit seeds are distributed by the animals that eat the seeds – fruit exist as an incentive to eat the seeds.
Seeds are indigestible, unlike the rest of the fruit, so it passes through the digestive system and ends up in poo, where it germinates using the nutrients from the poo.
Then it’s the normal plant growth cycle.
But if you’re asking how seeds know to germinate, then there’s a reason why plants (and seed banks!) know to keep their seeds dry. Seeds germinate (start growing) in the presence of water, since fertile soil is usually wet.
