Although‚ at much higher temperatures‚ plants close stomata to prevent excess water loss. b. The increasing humidity causes reduced transpiration rates. This is because atmosphere is saturated with water vapor and so not much can be absorbed by the plant as humidity increases. At 100 percent humidity‚ the plant cannot absorb any more water. In a dryer atmosphere (less humidity)‚ transpiration will happen much more rapidly. c. The rate of transpiration is related to whether the stomata

must be more to this story. In this laboratory you will be investigating how pressure affects the temperature of air and how this relates to the formation of clouds in the troposphere. You will form a cloud in a bottle‚ find the dew point and relative humidity of air at different places in the school and use a chart to estimate how high that air would have to rise to form a cloud. Part 1 In order to explore how clouds form in the atmosphere we have to examine the relationship between changes in air

Assume that you have 100 years of continuous temperature records from your local weather service office. Discuss some of the difficulties you might have trying to determine whether average temperatures have increased during this period. Our book indicated that one of the difficulties is that reporting systems have changed so much over time. Other things to consider are things such as time of observation adjustments‚ adjustments for changing equipment‚ and adjustments for changing site locations

IB Biology HL Y1 15 January 2009 The Effect of Humidity on Transpiration in Plants Problem/Aim How does placing a plant in a more humid location for 50 minutes affect its rate of transpiration? Introduction Transpiration is the loss of water from a plant‚ mainly through the stomata of leaves. Darkness‚ internal water deficit‚ and extremes of temperature tend to close stomata and decrease transpiration; illumination‚ ample water supply‚ and optimum temperature cause stomata to open and increase

all over again. Many factors affect how evaporation happens. If the air is already thick or saturated‚ there won’t be enough space in the air for liquid to evaporate quickly. When the humidity is at one hundred percent‚ the air is coated with water. No further water can evaporate when at one hundred percent humidity. If air pressure is high on the surface of the ocean‚ then the water will not evaporate easily. “The pressure pushing down on the water makes it difficult for water to escape into the

Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool‚ dark‚ damp microhabitats such as in rotting wood‚ under rocks‚ in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes‚ crickets‚ weta and spiders living. Woodlice

Abstract A investigation took place at a large mangrove community called the ’Badu Mangroves’. The interactions of organisms and the Badu Mangrove ecosystem were observed. While experiments were carried out to determine the abiotic ( e.g. temperature‚ humidity‚ soil pH ) and biotic ( e.g. number of seedlings distributed throughout a certain area‚ adaptations of animals ) features in the Badu Mangrove community. Aim The aim of this report was to explore the abiotic and biotic features concerning the growth

because that would cause the stomata to close. A high light environment was set up by placing the plant under intense light to simulate sunlight. Groups experimenting a humid environment misted the plant and wrapped it inside a sealed bag to increase humidity.
