Question: What environmental factors affect transpiration?

What are the 6 factors affecting transpiration?

The environmental factors affecting the rate of transpiration are:

  • Light,
  • Humidity,
  • Temperature,
  • Atmospheric pressure,
  • Wind speed or velocity.

What environmental factors are around the plant that increases or decreases transpiration?

Higher temperatures cause the plant cells which control the openings (stoma) where water is released to the atmosphere to open, whereas colder temperatures cause the openings to close. Relative humidity: As the relative humidity of the air surrounding the plant rises the transpiration rate falls.

What is transpiration and factors affecting it?

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 are the external factors which affect transpiration?

These include conditions of the environment which affect the rate of transpiration. The external factors are humidity, wind, atmospheric pressure, temperature, light and water.

What are the internal factors affecting transpiration?

IT\'S FUNNING:  Are coffee cups recyclable UK?

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 five environmental factors?

Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites.

What are the environmental factors that affect growth and development?

Over the past 100 years, the study of environmental influences on human physical growth and development has focused on the influences of social and economic factors; family and household characteristics; urbanization/modernization; nutrition; and features of the physical environment such as altitude, temperature and …

What are the factors that affect transportation?

  • Environmental. …
  • Historical. …
  • Technological. …
  • Political. …
  • Economic.

What are the factors affecting evaporation and transpiration?

The primary factors that affect the potential evaporation and transpiration, if water is readily available from soil and plant surfaces, are: Solar Radiation and Temperature. Humidity and Wind.

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.
