How is water necessary for the structure of a green plant?
ch4aika [34]
Like all life on earth, plants need water to survive and grow. Indeed, like humans, water is the primary element that makes up the structure of plants. Human bodies are comprised of around 70 percent water, but in plants this proportion can be as much as 95 percent. Water is also essential to the way a plant receives nutrients and provides energy for itself. Thus, water is arguably the most essential substance required by plants. That is why many elements of permaculture design – from using swales and contouring to slow runoff from the land and allowing it to sink into the soil to mulching to prevent evaporation of moisture from the soil surface – emphasis the preservation of water so that it can be provided to plants.

hope this helped :)

An eccentric millionaire botanist has offered a $25,000 scholarship to anyone who can successfully get a plant to grow through a
mars1129 [50]

Answer:

Option B, Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.

Explanation:

Options for the question are

A) Apply auxin directly to the shoot tip on the side to which you want the tip to bend.

B) Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.

C) Inject compounds that block auxin receptors into the part of the stem opposite from the direction you want the stem to bend.

D) Plant the roots in two different pots, and apply auxin to the root bucket that is on the same side as the direction you want the plant to bend.

Solution

Auxin is responsible for stem elongation by inhibiting growth of lateral buds. The movement of auxin is opposite to the direction of elongation of cells. Generally, Auxin moves to the dark side which is opposite to the direction i.e the lighter side in which cell elongate . Due to this growth pattern, the stem tip gets curved towards the light.  

Hence, option B is correct
