Answer 1

The word you are looking for is "planet" not "plant". A plant is a thing that grows in the ground, a planet is an object that orbits the Sun, and has cleared out its orbit of other junk like asteroids and Kuiper Belt objects.

Pluto is actually a Kuiper Belt object, not a planet. There are millions of Kuiper Belt objects (KBOs) - they are kind of like asteroids, but they exist beyond the orbit of Neptune, and they are mostly icy with bits of rock and dust mixed in. Because the Kuiper Belt is so far away, we don't know a whole lot about it, but we are learning more all the time. In fact, we have discovered KBOs that are *larger* than Pluto. And there are asteroids that are spherical, so that can't be the only thing that determines what a planet is or is not.

By the way, when the first few asteroids were discovered (1801), they were called planets. But after a while so many asteroids were being discovered that they realized they couldn't really call them planets, so they were demoted, just like Pluto was last summer.
