Why do the roots of a plant always grow down and the stem grows up?

In: Botany or Plant Biology [Edit categories]

Answer:

Its basically because of geotropism (when it grows downwards/follows gravity) plants always have their roots growing down because if they didn't grow down, they wouldn't support a plant very well. the stem always grows up, generally for the same reason, but also because the sun is up. phototropism comes into play here. plants always try to grow towards the sun, enabling them to have a good source~~. So the root grows downwards to get the nutrients/find the nutrients that the plant needs to grow and stay living.-(don't ask me y this part has a line through it!!)~~
