BOTANY

Detailed explanation-1: -Transpiration (evaporation) occurs because stomata are open to allow gas exchange for photosynthesis. As transpiration occurs, it deepens the meniscus of water in the leaf, creating negative pressure (also called tension or suction).

Detailed explanation-2: -During transpiration, water evaporates from tiny holes in the surfaces of leaves into the air. These tiny holes are called stomata. As water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots.

Detailed explanation-3: -Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.

Detailed explanation-4: -In plants, water enters the root cells by osmosis and moves into tubes called xylem vessels to be transported to the leaves. Water molecules inside the xylem cells are strongly attracted to each other because of hydrogen bonding (this is called cohesion).
