What happens to the water concentration inside a leaf during transpiration?

  1. It increases

  2. It remains constant

  3. It decreases

  4. It fluctuates slightly

During transpiration, water evaporates from the surfaces of the leaf, primarily through small openings called stomata. As water vapor leaves the leaf, it reduces the overall water concentration inside the leaf. This process creates a negative pressure that helps draw more water from the roots through the plant’s vascular system, promoting continuous water movement. Consequently, the concentration of water
