Abstract

The objective of this investigation was to determine the effect of one specific environmental condition on the rate of transpiration in plants. This particular investigation looked at the number of leaves in a plant and how it would affect the rate of transpiration in plants. The aim of this investigation was to find out if the larger the number of leaves a plant had, the higher the rate of transpiration would be.
The results from this investigation showed increased transpiration in the plants with the greater number of leaves compared to the ones with less leaves.
To determine the validity of …show more content…
Highlighted: Like in experiment one, plant 2(2 leaves) transpires more water than plant 3(4 leaves) does. Reason will be explained in discussion.
Note: Experiment two had the exact same materials and variables as in experiment one.
Differences: change in plant, 200mL starting point.
The reason for having a second experiment will be discussed in the

    Water molecules are present in the air as water vapor, they are never as abundant in the air as they are in the leaf. Thus, the plant loses water as it diffuses into the air through the stomates. This water loss is known as transpiration.…

    Transpiration is the loss of water vapor from land plants into the atmosphere, causing movement of water through the plant from the soil to the atmosphere via roots, shoot and leaves, which occurs mainly through the stomata. Factors which can affect the rate of transpiration are those such as temperature, humidity, wind, and light, and the water in the soil. A plant cannot continue to transpire rapidly if its water loss is not made up by replacement from the soil. When absorption of water by the roots fails to keep up with the rate of transpiration, loss of turgor occurs, and the stomata close. This immediately reduces the rate of transpiration (as well as of photosynthesis). If the loss of turgor extends to the rest of the leaf and stem, the plant wilts. To measure transpiration, you can artificially create the environment for a plant for which you want to transpire. For example, if you have a .1 mL pipette, plastic tubing and a leaf, you have almost all the materials you need to measure the rate of transpiration for that leaf and whatever environmental conditions you impose upon the leaf. One will be examining the amount of water in the tubing which is being used, and from there you can tell how much water has been used.…

    Abstract: Our group wanted to see how transpiration would happen in plants when they were in different environments. The different environments we used were humidity and room environments. We measured transpiration using the whole plant method. Our results showed that the plants in a humid environment had greater transpiration rates than the plants in the room environment.…

    Plant leaves are known to have a spongy mesophyll layer which usually contains CO2 and O2 gases within it, due to this leaves and leaf disks usually float in water. If leaves are placed in an alternate source of carbon dioxide in the form of bicarbonate ions, then photosynthesis can occur. When photosynthesis occurs, oxygen will accumulate in the air space of the mesophyll, causing the sunken leaf to become buoyant again. Cellular respiration occurs at the same time as photosynthesis in plant these, countering the processes and affecting the accumulation of oxygen in the air spaces. Therefore the buoyancy of leaf disks is an indirect measurement of the net rate of photosynthesis.…

    Anacharis and Rate of Transpiration

    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.…

    Transpiration Lab Report

    Our class data showed that the transpiration pull was the second highest in humidity and in the dark. This data is incorrect, in this given condition because in plants, transpiration is controlled by water potential. This change in water potential in leaves causes a gradient by which water can be moved upward. When the water potential of the air was increased by the humidifier and plastic covering, less water evaporated from the leaves, decreasing the water potential gradient between the root and stem, in turn decreasing the transpiration pull. These conditions should have shown little or no transpiring.…

    Effects of sunlight on leaves

    In preparing to determine the effect of sun on leaves two different plant species were chosen at random from a picture binder to be measured. Three sun leaves and three shade leaves of the same plant species were carefully measured using a small metric ruler starting at 1 cm and so on. This was done with two different plant species. Height and width of the leaf was measured, not including the stem of the leaf. After measuring all twelve of the leaves they were recorded into a table to be compared and contrasted.…
