Why do plants need water?

Question

Do plants absorb nutrients from the water itself or does the water dissolve nutrients in the soil which can then be absorbed by the plant?

Answer 1

It does both. Plants need water for many reasons:
1. Water is a solvent for biochemical reactions.
2. Water is required or produced by many biochemical reactions. For example it is a reactant in photosynthesis which plants need to make food
6CO2 + 6H20 --> C6H12O6 +6O2
3. Water flow helps transport mineral nutrients through the plant.
4. Water filled cells help support the plant, therefore plants deprived of water wilt.
5. About 95% of water absorbed by most plants is evaporated from the leaves (termed transpiration) because the stomata must be open to let in carbon dioxide needed for photosynthesis.

And I most certainly did not copy the answer of the person below me. That is ridiculous and thank you for defending me, Maverick.

Why Do Plants Need Water

Answer 3

Huhhh?

Water can and will dissolve minerals in the soil.
Dissolved minerals can and will be taken up by the plant with the water flow into the plant. For uptake by the plant, some nutrients require metabolic energy, while others are taken up more passively.

An element in its solid state normally cannot enter the plant. It MUST be soluble. It is possible to force solids into a plant by scraping and applying, or by injecting or "shooting" it into the plant.

Water is required for turgor, which is the water pressure inside the plant cells. Without turgor the plant wilts. Water pressure is also required for growth (it is the force that expands plant cells).

Water is required as an electron source for photosynthesis.

Water is the solvent of life.

Answer 5

H20 produces the nutrients the plants need while in the soil for the plants to grow,It's almost like putting water in a car battery and then the battery will produce more acid.

Answer 6

I will answer this differently. plants need water for nutrients and you already knew that. ANother reason why plants need water for turgor preasure (water preasure) to make up its cytoskelaton (skelaton). When a plant does not recieve water it droops and this is the reason why. The plant needs turgor preasure to prop itself up.

Answer 7

Plants need water so that they won't dry out. They also need water to absorb the moistness of soil surrounding them as well.

Answer 8

The question has been answered very well by 'matahari'

My doubt is quite different:-

1) How a person who has answered a question about 22 hours ago ( Almost as soon as the question was asked) can copy that answer from the answer that was given 14 hours ago? that is 8 hours later!

2) Why a person who has reached a level 4 would copy from a person who is just at level 1?

3) Why one would copy from the answer of a person who is careless slovenly and does not care to type ' copied' correctly?

Answer 9

Cause the water is essential to the photosynthesis (H2O+CO2= C6H12O6)

Answer 10

to grow
