They grow up due mostly to natural selection. Plants compete for sunlight. The ones that were less competetive have become extinct. The ones that grew up the fastest got the most sunlight and have proliferated around the world. you can see plants compete through the process of "sucession" in your local bushland. ground covers are generally out competed overtime by canopy species. so its built in genetical codes that the successful plants have developed over time ie they have evolved. As in occasionally plant shoots try to grow downwards, they die and don't set seed. the ones that grew upwards then set seed, and of course having the genetic data that says grow against gravity and to the light, That is the trait that it's seeds also will probly be born with.

Chloroplasts are not plants, but rather organelles found in plant cells that are responsible for photosynthesis. Seedless plants, like ferns and mosses, reproduce via spores, while seed plants reproduce via seeds. Chloroplasts are found in both seedless and seed plants, as they are essential for the process of photosynthesis.

When the seed soaks up water where does the water go?
Into the cells of the seed.
What is a young plant that has germinated from a seed?
A young plant growing in the seed is called the embryo. After some days the shoot bursts up from the seed and comes out of the ground. Underneath, the roots come out to transfer water.
How do you get a Rox seed on Moshi Monsters?
There are no Rox seeds on Moshi Monsters. When you plant a seed on Moshi Monsters, sometimes it just randomly turns into a Rox plant.

Wait until the plant is fully grown, then dig it up to collect the Rox.
