Why do a plants roots always grow downward and its shoots always grow upward?

Answer 1

as you prabably already know, plants feed souly off of soil, (dirt), and the roots will always be trying to gain more and more nutritions from the dirt, and will keep trying to go deeper.

(THAT ABOVE IS NOT POSTED BY ME)

*plants are gravitrophic meaning that the roots will always grow towards gravity and to of course absorb the nutrients, but there are some plants that do grow outside of of the soil like in pots and they still grow downward.

Answer 2

the stimulus in this case is gravity .

shoots grow up,away from gravity.

roots grow down,towards gravity.again auxin control this growth.

if a plant is put its side the auxin builds up on the lower side of the shoot and the root.

• in the shoot the auxin stimulates it to grow moreon the lower side
• this causes the shoot to bend upwards
• in the root the auxin also builds up on the lower side.but Ayxin slows down growth in a root
• so tht upper side of the root grows quicker than the lower side
• the root bends downwards

Answer 3

No, plants do not always grow downward. Plant roots always grow downward due to positive gravitropism or positive geotropism. Plant shoots always grow upwards due to negative gravitropism or negative geotropism.

Answer 4

You'll probably want to avoid material which would need much upkeep, and go with metals or plastic. This means that you should get a metal desk, and probably go with a plastic chair with easily cleanable cushion.

Answer 5

They usually grow upwards, but if the light source is further away from the plants, they tend to lean towards the source.

Answer 6

Plants do not grow in the direction of gravity. Though a plant's roots travel downward, the plant grows in the direction of the most sunlight, because sunlight provides the plant's energy.

Answer 7

Not always, downward growth takes place mostly in hanging plants such as Portulacaria etc.

Answer 8

Plants grow upward towards the light, their roots grow downwards
