Why do some apples have no seeds in them?

Answer 1

If you were to cut an apple in half cross sectionally you would find that an apple has five compartments. Each of these compartments should include a seed in order for the apple to be full sized and well shaped as the seeds produce hormones which allow the fruit to develop. Fruit which lack seeds often abort from the tree in times of stress. Varieties can have more than one seed in each carpel depending on the health and vigor of the tree. The healthier a tree is, the more potential seed the fruit can have per carpel.

If you want to produce a certain type of apple it is not probable to do this by planting a seed from the wanted type. The seed will have DNA from the apple that the seeds came from, but it will also have DNA from the apple flower that pollinated the seeds, which may well be a different type. This means that the tree which would grow from planting would be a mixture of two. In order to grow a certain type of apple, a small twig, or 'scion', is cut from the tree that grows the type of apple desired, and then added on to a specially grown stump called a rootstock. The tree that grows will only create apples of the type needed.

*Plants usually produce far more seeds than are needed. This is because many seeds don't survive and grow to maturity.

Answer 2

Seeds are for future generations of apples to grow, once the apple hits the ground and rots there are the seeds for some new trees.

Answer 3

apples grow off trees, and to produce more apples, the seeds are planted.

Answer 4

so that if new seeds land in the ground a new apple tree can grow

Answer 5

The apple has so many seeds so you can plant another one, that's what seeds are for.Right.

Answer 6

They don't, all the apples I have eaten in my life have had the same sort of seeds in their cores.
