There is a hormone produced in the shoot tips of growing plants which causes the cells forming behind it to elongate rapidly. This hormone is destroyed by light, you c…an see this because plants grown in the dark tend to grow tall and thin. If the light hits the side of the plant's growing stem then the cells on this side stay short while the cells on the side in the shadow elongate. This cause the tip of the growing plant to bend towards the source of the light. Thus plants, as they grow, lean towards the sun.
In fact the Earth is moving away from the Sun - due to the Suns mass loss - at a mere 15cm per year. That means that in a hundred years, we will be almost 15 metres further …away - hardly worth worrying about.
because they take sunlight from the sun so they turn towards the sun whoever asked this QUESTION is DUMB
The root of a plant holds it upright. Other parts of plant such as- leaves, fruits vegetables etc. (except roots), are hold upright by the stem.
Plants point towards the sun because they need the sunlight in order to live. Without sunlight they would die.
Plants grow toward the sun because the side of the plant that is shaded grows faster. Very simple concept; think about this. A plant is under (let's say) a bench and light shi…nes only one side. That plant heads toward the sun because the side without light is now grwoing faster, thus leaning toward the sun.
The sun moves and the Earth. But I doubt it moves closer-not too much- because it would be too hot for us to be here.
Heliotropism - see comments below .
Ok I belive its because the stem of the plant is pushing through gravity and also it help the top of the plant so the plant grows. --- Emster910 (On Roblox)
Is the sun does move east towards the moves does west.
