BERRIES.
Some berries, such as raspberries and strawberries, are so good they seem to grow on purpose to be eaten. Very likely they do.
It is quite necessary for the blackberry and raspberry bushes to have their seeds sown at some distance from the parent plants, and it is also an advantage to strawberries to have their seeds dispersed. So what is better than to get the help of the birds?
To this end the berries are sweet and juicy when ripe, and they are bright in color, so that the birds can easily find them. A bird often picks a berry and carries it somewhere else to eat, and often it eats only a part and leaves the rest, which falls to the ground.
All berries have seeds in them or outside of them. Strawberries have the little seeds on the outside, as you can easily see.
Bunchberries.
Gooseberries, currants, and grapes have the little seeds inside, but, whichever way it is, some of the seeds will be left or scattered about by the birds that eat the berries. If some of the seeds are swallowed, that does not seem to hurt them; like the mistletoe seeds, they are able to sprout after having been eaten by a bird.
