Water is essential for plant survival, as it is involved in many important plant processes, including photosynthesis, respiration, and transpiration. Water is taken up by plant roots and transported through the xylem tissue to the leaves, where it is used in photosynthesis to produce glucose and oxygen. Water is also involved in the transport of minerals and other nutrients throughout the plant. Additionally, water helps to maintain the turgor pressure in plant cells, which keeps the plant upright and supports the growth of new tissues.
