Accurate quantification of the movement of water into plants is possible with a potometer. Assessing the impact of changing humidity and air movement on plant uptake of water provides essential experience for understanding plant adaptations. Some species of plant develop with differing densities of stomata according to their environmental conditions. Measuring stomatal density provides a tool for investigating this variation.

1. A window on the past: Measuring stomatal density.
This procedure describes how to measure the density of stomata on a leaf epidermis. Use the method to collect data about stomatal density from plants grown in a range of conditions.

2.  Measuring rate of water uptake by a plant shoot using a potometer.
Potometers with fine capillary tubes are favoured apparatus for measuring transpiration rate from plant shoots. Other designs of apparatus are available.

3.  Estimating rate of transpiration from a plant cutting.
Measure total change in mass, or volume of water taken up to estimate the amount of water lost from a plant cutting by transpiration.

Materials used: Polyethene bag, Rubber Band, a Plant (any type)

Hypotheses: Assumption that the water will form on the polyethene bag because of transpiration

Experiment: Take a plant of any type then take a polythene bag and put it on one side of the plant then tie a rubber band so that it will not let the air escape. Leave it there for 2 or 3 hours.

Observation: I observed that after putting the polythene bag and leaving for couple of hours there was some water droplets forming on the polythene bag. This is due to the higher temperature formation inside the bag. Plants sweat to, but not because they are hot. They sweat to get rid of the extra water that they have no use of. Water travels through a plant from its roots to its leaves. Any excess of water is lost through pores in the plants leaves. When people sweat it is called perspiration. When plants sweat it is called transpiration. The plant gets rid of surplus water through stomata’s.

Data: The process of releasing excess water through the pores called stomata of a plant is called transpiration.

Conclusion:  Hypotheses is correct if we cover the plant with polythene bag it will give water droplets. The sweating of the plant is to get rid of the excess water through stomata.

I observed that after two days there were droplets of water present in the plastic bag this is because of transpiration , the plants  lose water, even though they are in the bags. We all know that plants need water. However, it only uses a small amount.  The rest is lost by transpiration (about 99%!!). It cools the plants, but it is also a critical part of the water cycle.  Transpiration adds a huge quantity of the water back into the air.                            By - Githu Jacob          Class - 6-0

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. But since I had covered the plants with a Polythene Bag, the drops of vapor fall and is collected in the bag.

When we pour water to the plant and leave it for two hours we will notice that water droplets have been formed on the polythene bag and has turned foggy from the inside. This is because of the leaves of the plant giving out excess water outside with the help of stomata  which is located under the leaves .This process is known as transpiration.

This experiment informs us about the process TRANSPIRATION.It is the process of water moving through plants and its evaporation from leaves,stems and flowers .We know that plants need water however it uses a very small amount the rest is lost by transpiration (about 99%).Leaves have pores all over them that you can see on the bottom side of a leaf if you use a magnifying glass.These pores are called stomata. The plants open their stomata to let in carbon dioxide and water comes out in the process.It cools the plant ,it is also a critical part of the water cycle .Transpiration also adds a huge quantity of water back into the atmosphere.We use a polythene cover so that the water does not get absorbed into the atmosphere so that we can see the process and polythene does not absorb water .If you cover a plant with a polythene bag due to transpiration you will notice water droplets on the polythene cover.I think that there are more chances of rain in areas with more trees' as the trees' exert more water than they utilize hence more moisture is released back into the atmosphere so the water then is converted into clouds which then results in rain

ANS 1) I have observed that there are water droplets present in the polythene bag due to transpiration.
Transpiration is the process by which a plants lose water through small holes in their leaves called stomata .
)Transpiration helps in cooling the leaves.
)During transpiration , water is pulled upwards from the roots to  compensate the lose of water.
)transpiration plays an important role in the water cycle.

I infer that transpiration also is a important/vital process in a plant such as photosynthesis

1. What do you observe on the polythene bag after two days?

2. What do you infer from the observation?
After two days we observe that there are water droplets on the polythene bag because of transpiration.Transpiration is the process by which leaves lose water from small pores called the stomata.
Transpiration helps the leaves to cool down and the water is pulled upwards from the root,it also carry's nutrients within the plant.thus this is a vital process for plants . Transpiration is very important in the water cycle.

# data[].attributes.body
The experiment is about the process TRANSPIRATION .
transpiration is the process by which plants lose water in their leaves through small pores called stomata . These pores are the reason to how plants take in carbon dioxide and give out oxygen.They lose water too from these pores.This statement tells us why there were water droplets present on  the polythene bag.The plant releases water from these pores as usual but the water does not escape, it gets trapped in the polythene cover. See this is the reason.I infer that along with photosynthesis, transpiration is also a vital process for plants.

# data[].attributes.body
During the experiment I found that there were small water droplets on the inside of the polythene bag.
This is because of transpiration. Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves.

# data[].attributes.body
I observed that during transpiration experiment, the plants will lose water, even though they are in the bags.
Although we may not be able to see them, plants have small pores, or holes, on their leaves. I looked at the bottom of a leaf under a microscope, and was able to see these holes, which are known as stomata. This is where plants can lose water through transpiration.

Transpiration happens in part because plants need to breathe. Plants need to take in carbon dioxide, and to do this, they need to open their stomata. When this happens, water comes out.

# data[].attributes.body
There will be tiny droplets of water inside the polythene bag.
This is due to a process called transpiration.Transpiration is the evaporation of water from plant leaves.Her the transpired water condenses on the inside of the bag.

ResultsIf the plant cannot receive a fresh supply of air, it will not get the carbon dioxide it needs to live and eventually it dries out.If there is enough fresh air, the plastic could still either block the sunlight or could allow water vapor to build up around the leaves or on the plastic. The water evaporates and you have water droplets left. The air will become humid and warm. The water lost  by transpiration will be trapped in the bag. Water droplets can be seen on inner surface.

Observation- I saw tiny water droplets on the polythene bag, it also looks very foggy
Conclusion- when the stomata on the leaves gives out the water which is not needed, the Sun makes it evaporate and the gas was trapped in the bag, and after sometime it cooled hence, it made it look foggy and there was tiny water droplets on the polythene bag. The process by which the stomata on the leaves gives out water which is not required for it to grow or perform photosynthesis, etc. is called transpiration.

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97-99.5% is lost by transpiration and guttation.

conclusion-we cant see the water exit through the stomata
because the stomata exits the water as water vapour.This begins when the leaves have more water it gives out through stomata.This process is called transpira

Ans 1.. There were water droplets on the polythene bag.

Ans 2 .. this happened because of transpiration, when the leave have more then required water, it gives out the water through stomata, and because of the sunlight the water evaporated and reached till the plastic polythene and condensed. Hence we can find water droplet in the polythene bag.

Conclusion : We can't usually see the water that exits a plant during transpiration. This is because the water is in the form of a gas known as water vapour. Thus the bag traps the water vapour and converts it back into water. The water therefore,appears as condensation on the inside of the bag.
