Answer: Water serves as a solvent for the minerals and nutrients that plants absorb through their roots. This allows these nutrients to be transported throughout the plant, providing it with the resources it needs to grow and thrive. Secondly, water is a crucial component of photosynthesis, the process by which plants produce energy from sunlight. Without water, plants cannot produce energy and will eventually die. Thirdly, water helps regulate the temperature of plants, preventing them from overheating in hot conditions.
