why do plants and trees grows vertically towards the sky?

Question

fallen coconut trees after a big storm along the seashore grows back towards the sky.

Answer 1

Phototropism
Phototropism is directional plant growth in which the direction of growth is determined by the direction of the light source. It was formerly called heliotropism. Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is a positive phototropism, while growth away from light is called negative phototropism (or Skototropism). Most plant shoots exhibit positive phototropism, while roots usually exhibit negative phototropism, although gravitropism may play a larger role in root behavior and growth. Some vine shoot tips exhibit negative phototropism, which allows them to grow towards dark, solid objects and climb them.

Answer 2

They climb towards the sun. If you have a potted plant place it sideways for a week it will start growing up or toward the sun then turn it back again the same thing they reach for the sun...

Answer 3

They are growing towards the light, which provides their energy. No light/energy ultimately = no food. The plants need to get their leaves/green photosynthesizing parts into the light ASAP so they can start collecting enough energy to live & grow!

Answer 4

I think it has something to do with photosynthesis. Plants and trees always face the sun because that's there source of food and energy.

Answer 5

Heliotropism, movement or growth in response to sunlight

Phototropism, movement or growth in response to light

other tropisms

Chemotropism, movement or growth in response to chemicals
Geotropism or Gravitropism, movement or growth in response to gravity
Hydrotropism, movement or growth in response to moisture or water

Thermotropism, movement or growth in response to temperature

Answer 6

up in the sky is where the answer is for everything...look at that and learn!.....that`s where i`m aiming too!....up there somewhere!..................get it?!
