Why do plants need a lot of water?

Green plants are known for their ability to photosynthesise. Water is essential to this process; it enters the plant's body through the leaves, where photosynthesis occurs, and transpires the remaining water as the plant exchanges carbon dioxide.

Water is necessary for plants for a number of reasons: 1. Photosynthesis: Water is essential to photosynthesis, which is the process by which plants convert sunlight into energy. It is used to transport nutrients and dissolved minerals from the soil to the leaves where photosynthesis occurs. 2. Nutrient uptake: Water aids in the uptake of essential nutrients from the soil through the roots of plants, which are vital for plant growth and development. 3. Turgor pressure: Water keeps the turgor pressure within plant cells stable, allowing the plant to remain upright. 4. Cooling: Plants can also use water to cool themselves through transpiration, which is the process by which water evaporates from leaves and helps to regulate the temperature of the plant. In summary, water is necessary for the proper functioning and survival of plants.
