Chapter 3: Problem 2

What term describes the release of water vapor from the leaves of plants? A. evaporation B. precipitation C. transpiration D. condensation

Short Answer

Expert verified
C. transpiration

Step by step solution

01

Understand the Question

The question asks for the term that describes the process by which water vapor is released from the leaves of plants.
02

Define Each Term

It's important to know the definitions of each option:- Evaporation: The process by which water turns into vapor and rises into the atmosphere.- Precipitation: The process by which water falls from the atmosphere as rain, snow, sleet, or hail.- Transpiration: The process by which water vapor is released from the leaves of plants.- Condensation: The process by which water vapor turns into liquid water.
03

Match the Definition with the Question

Compare the definitions with the process described in the question. The process that matches 'the release of water vapor from the leaves of plants' is transpiration.
04

Select the Correct Answer

Based on the definitions and the match, the correct term is transpiration.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

water cycle
The water cycle, also known as the hydrologic cycle, is a continuous process where water moves through different states and locations on Earth. It involves several key processes:

  • *Evaporation*: Water from oceans, lakes, and rivers turns into vapor and rises into the atmosphere.
  • *Condensation*: Water vapor cools and forms tiny droplets, creating clouds.
  • *Precipitation*: Water falls from clouds back to Earth as rain, snow, sleet, or hail.
  • *Run-off and infiltration*: Water flows over the ground or seeps into the soil, replenishing groundwater and eventually reaching bodies of water.

Transpiration is an essential part of the water cycle. When plants release water vapor from their leaves, it contributes to the overall movement of water in the environment.

Understanding the water cycle helps us appreciate how water is naturally recycled and distributed across the planet. This knowledge is important for managing water resources and predicting weather patterns.
plant physiology
Plant physiology studies how plants function. One important process in plant physiology is transpiration. Let's break down how transpiration works and why it's vital for plants.

  • **Root Absorption**: Roots absorb water from the soil through tiny structures called root hairs.
  • **Transportation**: The absorbed water travels upwards through the plant inside tubes called xylem.
  • **Leaf Release**: Water reaches the leaves and is released into the air through small openings called stomata.

Transpiration helps in cooling plants, much like sweating cools humans. It also helps transport nutrients from the soil to different parts of the plant.

The regulation of stomata openings ensures water balance within the plant, making it a complex and fascinating process in plant physiology.
vapor release
Vapor release in plants, specifically via transpiration, is crucial not only for plants but also for the environment.

Here are some key points about vapor release:

  • **Cooling Effect**: When water evaporates from the leaf surface, it cools the plant, protecting it from overheating.
  • **Humidity Regulation**: Transpiration releases moisture into the air, helping to maintain environmental humidity levels.
  • **Gas Exchange**: Alongside vapor release, plants also take in carbon dioxide and release oxygen through stomata, aiding in photosynthesis and respiration.
  • **Nutrient Transport**: As water travels from roots to leaves, it carries essential nutrients, making sure the plant gets what it needs for growth.

When learning about vapor release, it's helpful to visualize a plant in a process where it 'breathes' out water vapor, demonstrating its intricate role in both plant health and the broader ecosystem.
