What are four environmental factors that affect transpiration?

What are the 4 factors that affect the rate of transpiration?

Rate of transpiration

  • temperature.
  • humidity.
  • wind speed.
  • light intensity.

What environmental factors affect transpiration?

Transpiration is affected greatly by the environment factors such as temperature, light relative humidity, wind, and so on.

What are the 4 types of transpiration?

Depending upon the plant surface transpiration is of the following four types:

  • Stomatal Transpiration:
  • Cuticular Transpiration:
  • Lenticular or Lenticellate Transpiration:
  • Bark Transpiration:

What are the factors affecting the role of transpiration?

Various environmental factors, such as the presence of light, relative humidity, temperature, wind speed, availability of water, and cellular factors like the orientation of leaves, number of stomata, cuticles, and lenticels affect transpiration.

What is transpiration and factors affecting transpiration?

The cellular factors affecting the rate of transpiration are: The orientation of leaf, The water status of the plant, Structural Peculiarities of the leaf, Total number and distribution of stomata in a leaf.

Does wind affect transpiration?

Wind and air movement: Increased movement of the air around a plant will result in a higher transpiration rate. Wind will move the air around, with the result that the more saturated air close to the leaf is replaced by drier air.

What are environmental factors?

Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites. The diversity of environmental stresses that have been shown to cause an increase in asymmetry is probably not exclusive; many other kinds of stress might provide similar effects.

Does light affect transpiration?

Light intensity: The transpiration rate is increased due to the increase in light intensity. During daytime in the sunlight, the rate of transpiration is faster. … During dark, the stomata are closed, and hence transpiration hardly occurs at night.

What are the types of transpiration?

Transpiration is of following three types: Stomatal transpiration. Cuticular transpiration. Lenticular transpiration.

What is transpiration types of transpiration?

There are three kinds of transpiration: stomatal transpiration, cuticular transpiration and lenticular transpiration.

What are the three kinds of transpiration explain in brief?

The three major types of transpiration are: (1) Stomatal Transpiration (2) Lenticular Transpiration and (3) Cuticular Transpiration. Transpiration mainly takes place through surface of leaves. It is known as Foliar transpiration (more than 90%).

How do different factors affect the rate of transpiration?

The rate of transpiration can be affected by: light intensity, air movement, temperature and humidity. Increased light intensity will increase the rate of photosynthesis so more water is drawn into the leaves where photosynthesis primarily takes place and therefore the rate of transpiration is greater.

Which is not a factor affecting transpiration?

Some internal factors also affect rate of transpiration e.g., leaf area, leaf structure and age of plants. Chlorophyll content of leaves does not directly affect rate of transpiration.

How does temp affect transpiration?

As temperature increases, the water holding capacity of that air increases sharply. … Because cooler air holds less water, its relative humidity increases or it is ‘moister air’. Therefore, warmer air will increase the driving force for transpiration and cooler air will decrease the driving force for transpiration.
