Aim: We have been told to germinate and monitor a special seed (Cress Seed which is also known as the Mung seed) through out many stages of temperature, water level, amount of light and etc...

Safety

You must always wear goggles when handling chemicals. Glass is very dangerous when it breaks as it is sharp and can shatter to very thin small pieces.

Method:

We took six test tubes and put equal amounts of cotton into each test tube.

Then we put three Mung seeds in each test tube.

In test tube No.1 did not attain anything and see what will happen.

In test tube No.2 we added water and we also kept it in light.

In the test tube No.3 we added water and put that test tube in the fridge and see what happens.

In the test tube No.4 we added water and put the test tube in the dark. (Fully closed up cardboard box)

In the test tube No.5 we added water and NPK (nitrogen, phosphorus, potassium).

In this last test tube, test tube No.6, we to put 0.01mm of Hcl and kept it in the light.(Under a light bulb) After six days we checked to see the result.

Controlled Conditions

The controlled condition which we must limit is the amount of seeds, water and light.

Observation: I observed the 6 test tubes and these are the results that I came up with after 6 days.

The first test tube after six days had not grown and showed no progress.
As you may have imagined, due to the surroundings and environment that the mung seed was kept in, only the shoot grew 2cm.
In the third test tube nothing had changed.
In the fourth test tube the length of the shoots were 3.5cm, the width of the leaf was 0.4mm, the colour of the only one leaf which was there was light green, probably due to lack of Sunlight.
In the fifth test tube the length of the shoot was 2cm and ...

The first test tube after six days had not grown and showed no progress.
As you may have imagined, due to the surroundings and environment that the mung seed was kept in, only the shoot grew 2cm.
In the third test tube nothing had changed.
In the fourth test tube the length of the shoots were 3.5cm, the width of the leaf was 0.4mm, the colour of the only one leaf which was there was light green, probably due to lack of Sunlight.
In the fifth test tube the length of the shoot was 2cm and the rest had not changed.
In the last test tube the length of the shoot was 1.5cm and there was no other change which was visible.

The results taken after fifteen days were as follows:

The first test tube that was dry still had no changes.
The shoot of the second test tube was 10.2cm the width of the leaf was1cm, the colour of the leaf was green and the numbers of leaves were nine.
The third one that was kept in the fridge still had no change.
In the fourth test tube the length of the shoot was 25.5cm, the width of the leaves were0.5mm, the colour of the leaf were yellow and the number of the leaf were four.
In the fifth test tube the length of the shoot was 11cm, the width of the leaves were o.5mm, the colour of the leaves were green and the number of the leaves were nine.
In the last test tube the length of the shoot was 5.9cm and the width of the leaves were 0.6mm, the colour of the leaves was green and the number of the leaves was four.

Discussion

Plants are green due to the sunlight which gets absorbed by pigments called chlorophyll. They make up chloroplast and make the plants look green; these help the plant to make its food Glucose. This process is called Photosynthesis.

Results

In the first test tube there was no change at all because it was completely dry and plants need water to grow, germinate and various other process.
In the second test tube the result was awful because it did not have all the minerals, which a plant needed for better growth.
In the third test tube there was no change because the plant was kept in the fridge where it was too cold, plants grow best in normal, suitable conditions.
The fourth test tube was kept in the dark where there was no light where as plant need light to grow healthy and this is why they did not have the green colour as I described above.
The fifth test tube grew well because it had all the minerals, which a plant needs for a better growth, which is Nitrogen Phosphorus and Potassium.
The last test tube grew well but it could have had improved if it had all the three minerals.

The most suitable conditions for the plant were test tube 5 because it had all the minerals, which a plant needs. It grew well had nice colour, good width and length and was very healthy.

Observations of the results: I found that the plant which was left in the dark grew very ling indeed. This is because naturally when the plant is with the soil it grows up trying to reach the surface and sun. This is what happened here but the difference was there was no surface too is found hence it increased on and on.

Performance: The performance was very good as the results came exactly to what was planned and i found that there is no real use of accuracy as if you did this experiment anywhere with the same properties addressed to each seed you would attain the same result.

The performance is superb as we attain everything we required.

Errors and Adaptations made: We are not able to see light from the sun 24 hours a day and some days the sun does not come out much anyway (an error), so instead we put all the mung seeds under a light bulb which gave same results(adaptations).

We also put the mung seed which was meant to be in the dark in a fully sealed ox which did not let any light insert in to it. We also put it in the closet. This was very helpful as it was very easy and the results were much better.

Scientific knowledge and understanding: I know, from previous experience, that water is essential for the seed to grow. The sun helps the plant to create food through the process of photosynthesis. If water and light is not present the plant grows different to what is intended.

Some seeds are always slow at growing but the mung seed is very quick. The results we obtained were perfectly according to the should happen if the elements are missing.

If light is not available than the seed plant always climbs higher in search of it.
If water is not available then the minerals required will also not be and the seed will not grow at all.

In real life situation: In real life people have come up with methods in which they attain the best most suitable plants available through playing around with the properties required.

In a green house they have bulbs which give all the light available, which we also did in our own way, sprinklers which give water to plants on regular basis. The soil used is also filled with minerals to help better growth.

We were only testing and the results we found show that this is very good way to help better growth and quality. Our situation was different as we did not use mineral soil.
