Introduction

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: 1. We took six test tubes and put equal amounts of cotton into each test tube. 2. Then we put three Mung seeds in each test tube. 3. In test tube No.1 did not attain anything and see what will happen. 4. In test tube No.2 we added water and we also kept it in light. 5. In the test tube No.3 we added water and put that test tube in the fridge and see what happens. 6. In the test tube No.4 we added water and put the test tube in the dark. (Fully closed up cardboard box) 7. In the test tube No.5 we added water and NPK (nitrogen, phosphorus, potassium). 8. 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) ...read more.

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.

Conclusion

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. ?? ?? ?? ?? Raja Jamal Ali Unit 3 0145 ...read more.
