Which of the following accurately describes the correct order of events in the process of transpiration within a plant? a. water enters the roots, passes through the leaves, and leaks through the stem pores. b. water enters the roots, gets transported through the stem, and evaporates through the leaves. c. water is absorbed through the leaves, is transported through the stem, and nourishes the roots. d. water is absorbed through the leaves, nourishes the roots, and leaks through the stem pores.

B. Water enters the roots, gets transported through the stem, and evaporates through the leaves.

Explanation:

Transpiration is a process through which nearly 99% of water of the plant is lost into the environment. The process of transpiration serves as the defense mechanism in a plant body which protects the plants from heat radiations of sun and produces cooling effect. Water is initially absorbed by the plant with the help of its roots. This water then moves against gravity in the upward direction due to transpiration pull through xylem tissue of stems. Water moves upward and reaches various parts of the plant including leafs. From leafs this water evaporates into the atmosphere. The sun rays falling on the leafs are utilized in evaporating this water rather than damaging the plant. So, transpiration is a type of defense mechanism in plants.

Apart from this transpiration also helps in gaseous exchange and flow of minerals within a plant body.

your answer is going to be physical weathering
