Why is it important for stems to grow upwards?

Phototropism. Phototropism refers to the orientation of a plant in response to a light stimulus. In addition to gravitropism, which helps the roots go downwards, the stem demonstrates positive phototropism by growing in the direction of light. … Consequently, the shoot grows/turns towards the direction of light!

What would happen if we break the stem of a plant?

What causes unequal growth in plant stems?

In a stem, the shaded side contains more auxin and grows longer, which causes the stem to grow towards the light. … It grows because the auxin causes the cells to elongate on the shaded side, so this side grows more.
