The Story
Why Water Is Essential
Water is essential for plant life. It is a reactant in photosynthesis. It dissolves and transports nutrients. It maintains turgor pressure.
Photosynthesis is the process by which plants make food. It requires water, carbon dioxide, and sunlight. The water is split, and the oxygen is released. The carbon is used to make sugar.
Nutrients are transported through the plant in water. The water dissolves minerals and moves them from the roots to the leaves.
Turgor pressure is what keeps plants upright. Water fills the cells, creating pressure. Without water, the cells lose pressure. The plant wilts.

Water is the bloodstream of the plant. It carries nutrients. It maintains structure. It makes life possible. The next time you water a plant, remember: you are not just giving it a drink. You are keeping it alive.
Quick answers
Common questions
How much water do plants need? +
It depends on the plant. Some plants need a lot of water. Others need very little.
Can plants get too much water? +
Yes. Overwatering can drown the roots and cause the plant to die.
