Low, so that there would be less moisture lost. Because of the fact that there is not an abundance of water in the desert environment, Cacti require low transpiration. They do this by having smaller amounts of stomata. I would double check on that using other resources, but it is a fairly simple concept. Cacti need to hold in more water than other plants so they have lower transpiration rates. :)
What else can I help you with?
Which conditions will transpiration occur quicker than the control and why?
Transpiration will occur quicker in conditions of high temperature, low humidity, and high light intensity compared to the control. This is because higher temperatures increase the rate of water evaporation from leaves, low humidity creates a steeper concentration gradient for water vapor to diffuse out of the leaf, and high light intensity boosts photosynthesis, leading to increased transpiration to support metabolic processes.
In what climate region can cacti be found?
Cacti are typically found in arid and semi-arid regions, such as deserts and dry grasslands. They are well-adapted to thrive in high temperatures and low rainfall conditions.
What environmental factor has the greatest effect on transpiration?
The environmental factor that has the greatest effect on transpiration is humidity. High humidity levels reduce the rate of transpiration because there is already a lot of moisture in the air, making it harder for water to evaporate from the plant's leaves. Conversely, low humidity levels increase transpiration as the drier air creates a larger gradient for water to move out of the plant.
When is the transpiration stream fastest?
The transpiration stream is fastest during warm, sunny days when temperatures are high and humidity levels are low. This is because increased light enhances photosynthesis, leading to higher water uptake by roots and subsequent evaporation from stomata. Additionally, wind can increase transpiration rates by removing the moisture-laden air near the leaf surface, creating a steeper water vapor gradient. Overall, optimal conditions for transpiration include warmth, low humidity, and adequate light.
Why are stomata absent or present in low numbers in the upper epidermis?
To minimize the rate of transpiration
What desert would have variable temperatures low cacti and other succulents?
All the deserts of the Americas fit that description as cacti are only natives to this area of the world.
How does a type of plant affect transpiration?
*stomata -open-increased transpiration -closed-decreased transpiration *consequence of gas exchange -tradeoff of more gas exchange resulting in more transpiration *environmental factors -humidity -air movement -evaporative cooling -wind stress -intense light/heat
What atmospheric contribute to the highest rate of transpiration?
Factors such as low humidity, high temperature, and windy conditions contribute to the highest rate of transpiration in plants. Low humidity creates a larger gradient for water to move from the plant to the atmosphere, high temperatures increase the kinetic energy of water molecules, and windy conditions help remove water vapor from around the plant, promoting transpiration.
Which conditions will transpiration occur quicker than the control and why?
Transpiration will occur quicker in conditions of high temperature, low humidity, and high light intensity compared to the control. This is because higher temperatures increase the rate of water evaporation from leaves, low humidity creates a steeper concentration gradient for water vapor to diffuse out of the leaf, and high light intensity boosts photosynthesis, leading to increased transpiration to support metabolic processes.
In what climate region can cacti be found?
Cacti are typically found in arid and semi-arid regions, such as deserts and dry grasslands. They are well-adapted to thrive in high temperatures and low rainfall conditions.
What factors can cause an increase in the rate of transpiration?
Factors that can cause an increase in the rate of transpiration include high temperatures, low humidity, increased air movement, and intense sunlight. These conditions can lead to faster evaporation of water from plant leaves, resulting in higher transpiration rates.
What kind of soil goes best with most cacti?
Sandy soil without water logging and good drainage, with low organic content goes best with cacti. Sandy soil without water logging and good drainage, with low organic content goes best with cacti. Sandy soil without water logging and good drainage, with low organic content goes best with cacti.

What atmospheric conditions contribute to the highest rate of transpiration?
High temperatures, low humidity, and good air circulation all contribute to the highest rate of transpiration in plants. These conditions increase the rate of evaporation from the stomata on the plant's leaves, leading to more water loss through transpiration.
What type of vegetation region has sparse plant life with scrub brush and cacti?
A desert vegetation region typically has sparse plant life with scrub brush and cacti. These regions are characterized by low precipitation levels and high temperatures, which are ideal conditions for plants that have adapted to conserve water, such as cacti and other succulents.
Where do cacti grow most commonly?
in arid places with very low water.
