Plant-water relations are how plants regulate the hydration of their cells. This includes: Water collection: Plants absorb water from the soil, stems, leaves, and root hairs. Water transport: Plants transport water throughout the plant. Water loss: Plants lose water through evaporation from their leaves. Plants need more water than their metabolic needs. Through transpiration, plants release around 90% of the water they absorb from the soil into the atmosphere. Water is essential for photosynthesis, which is how plants use energy from the sun to make their own food. During...

Water is essential for photosynthesis, which is how plants use energy from the sun to make their own food. During photosynthesis, plants use hydrogen from the water they absorb through their roots and carbon dioxide from the air. They release oxygen as a byproduct. Water is also important in the vacuoles of plant cells. It exerts pressure on the cell wall and protoplasm, which maintains the rigidity of the plant's roots, leaves, and other organs. Show less
