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.
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.
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.
The Earth isn't moving towards the Sun. The Earth's orbit around the Sun is slightly elliptical and not perfectly circular. So the distance between Earth and Sun does vary a b…it during the orbit, but the average distance stays the same at about 93 million miles, year after year.
yes they do
to maximize their energy input.
Photosynthesis No, this is called phototropism
plants lean towards the sun to gain nutrients, that is an adaptation. They also use th sun photosynthesis plants lean towards the sun for photosynthesis. When they …leann towards the sun it is an adaptation
