Because it’s the best form optimize content using as less surface as possible! A plant will try to put as much feeding material (either to feed the seed or hoping than an animal will eat it and transport the seed).

That is also why teapot are usually round : more tea inside and less contact with exterior world leads to less heat loss!

As well as the space optimisation thing, it’s also to do with how they grow. If something grows outwards from a point (the pollinated flower – or whatever) then it’ll expand as a sort of ball shape, since each point on the surface of a sphere is the same distance from the centre.

Other things instead grow in an elongated shape as they are growing in a particular direction.
