What is the term for biologically mediated transfer of water to the atmosphere, primarily by plants? A) Evaporation B) Transpiration C) Precipitation D) Infiltration
Answer (1)
The term for the biologically mediated transfer of water to the atmosphere, primarily by plants, is Transpiration . Therefore, the correct answer is B) Transpiration.
Transpiration is a process that occurs when plants absorb water through their roots and then release it as water vapor through small openings in their leaves called stomata. This is an essential part of the plant’s water regulation system and plays a crucial role in the water cycle.
Here's a step-by-step explanation of the process:
Absorption of Water: Roots of the plants absorb water from the soil.
Transport of Water: The absorbed water travels through the plant via a vascular system called xylem, reaching the leaves.
Release of Water Vapor: At the stomata, tiny pores mostly found on the leaves’ surfaces, the water is released into the atmosphere as water vapor.
Transpiration serves several functions:
It helps in cooling the plant.
It aids in the uptake and transport of minerals and nutrients from the soil.
It maintains the flow of water from roots to leaves, ensuring continued photosynthesis and nutrient distribution.
This process is a vital link in the hydrological cycle, contributing significantly to the movement of water in the ecosystem and affecting local and global climate patterns.
