EVERYDAY SCIENCE

Detailed explanation-1: -Damage to the xylem results in a decrease in the flow of water and nutrients throughout the tree. 2. The tree must first start performing photosynthesis in order to make up for the lost nutrients.

Detailed explanation-2: -The plant would lose its ability to carry out photosynthesis.

Detailed explanation-3: -If the xylem of the plant is removed, upward movement of water will stop leading to wilting of leaves and ultimately causes the death of a plant. In the absence of water, the plant will not be able to prepare food and also perform other essential activities.

Detailed explanation-4: -Transpiration is ultimately the main driver of water movement in xylem. The cohesion-tension model works like this: Transpiration (evaporation) occurs because stomata are open to allow gas exchange for photosynthesis.

Detailed explanation-5: -Plants absorb water and nutrients through the xylem: a tissue made up of thin tubes located just below the surface of the plant’s stems. The molecules in this tissue attract water molecules from the soil, so that the water is pulled upwards.
