Answer: Plants need water to absorb nutrients from the soil . Transpiration is the process by which water moves up the stem of a plant from root to leaf when water is lost from the plant due to evaporation occurring at the leaves.
Why is water important for plants Short answer?
Water is essential for crop production . Water is required for the germination of seeds and as soon as growth starts water serves as a carrier in the distribution of mineral nutrients and plant food. Plant cells grow by increasing in volume and for the cells to increase in volume they must take up water.
Why do plants need water short answer?
Plants need water for photosynthesis . Absorbed by the roots, water travels through a plant's stems to the chloroplasts in the leaves. Water also helps move nutrients from the soil into the plant. Too little water can cause a plant to wilt or droop.
Why do plants need water for grade 4?
The roots of the plant absorb water from the soil . This water carries nutrients from the soil to all the parts of the plant. ... The roots will then absorb the water for the plant. Remember: a plant needs water, sunlight and carbon dioxide to make food.
Why do plants need water mention any five points?

When a plant is properly hydrated, there is enough water pressure to make the leaves strong and sturdy; when a plant doesn't get enough water, the pressure inside the stems and leaves drops and they wilt.
Is water important for life?
Water's extensive capability to dissolve a variety of molecules has earned it the designation of “ universal solvent ,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water's role as a solvent helps cells transport and use substances like oxygen or nutrients.
Which water is important for plant?
Water helps to maintain the turgidity of cell walls . Water helps in cell enlargement due to turgor pressure and cell division which ultimately increase the growth of plant. Water is essential for the germination of seeds, growth of plant roots, and nutrition and multiplication of soil organism.
What do plants use water for?
Water is necessary for photosynthesis , which is how plants use energy from the sun to create their own food. During this process, plants use carbon dioxide from the air and hydrogen from the water absorbed through their roots and release oxygen as a byproduct. This exchange occurs through pore-like stoma on the leaves.
Do plants need oxygen survive?
The two primary reasons plants need is air to photosynthesize (make food) and to breathe. Plants need to breathe for the same reason people and animals must breathe – they need oxygen to convert food into energy . The relationship between air and indoor plants is crucial to keeping your plants looking their best.
Can plant live without air?
Plants breathe oxygen that they absorb from the air. Plants absorb carbon dioxide from the air to use during photosynthesis. Air is absorbed into the roots of the plants to provide the necessary oxygen. Air is not essential for a plant's growth; they can live without it .
What plants can survive without oxygen?
There are a lot of *bacteria* in wetlands that can live without oxygen, but all of the plants (vascular plants, mosses, even algae ) definitely require oxygen.
What happens to the plant if it is not watered for 2 3 days?
If a plant did not receive water for two days nothing will happen when you do not pour water more than three days definitely they would die . Because water is essential for plants. ... If they will not get much amount of water plants will shrink and plants will be incapable to accomplish the photosynthesis process.
What are the three ways in watering plants?
- Location and Timing. ...
- Drip Irrigation. ...
- Sprinkler Irrigation. ...
- Watering by Hand. ...
- Watering Shrubs and Trees.
When should we not water the plants?
