1.0 Introduction
Apart from the food they manufacture, plants also need carbon, hydrogen and oxygen to survive. Water absorbed from the soil provides the hydrogen and oxygen. During photosynthesis, carbon and water are used to synthesize food. They also need nitrate to make amino acids (Amino acid an ingredient for making protein). In addition to that, they need magnesium to make chlorophyll. Apart from all these sunlight to make their food in the process of photosynthesis.
1.1 Statement of problem
If we don’t have light it a problem for organism because all organism want light example plants, plants need light for photosynthesis. Human need light if no light we can see.
1.2 Objectives
To show that sunlight is necessary for photosynthesis.
Specifically to: Show photosynthesis of plants if we don’t have light how to we get oxygen and plants can’t to get carbon dioxide
Hypothesis: Light it important because light it give energy give to plants photosynthesis. And plants will release oxygen to organism.
1.3 Significance of the project
Plants will photosynthesis. Human respire want oxygen and release carbon dioxide. Plants want carbon dioxide and release oxygen. So plants must photosynthesis. 2.0 Method
Materials
-Plants,-Glass,-Candle,-Lighter,-box
Procedure
We have 3 glass for a plants. First glass we bring glass cover plant for a period of five days. But we took it outdoors. And then we took lighted candles put to the plant in a glass. Second glass bring glass cover plant for a period of five days. But we took it in box. And then we took lighted candles put to the plant in a glass. Third We lit a candle. And we bring glass cover plant.
2.1 Data analysis and presentation of results
First glass has a fire because a plant it has oxygen it help to fire and a light that causes photosynthesis of plant. Second glass no fire because no light for plant photosynthesis and no oxygen it be no fire. Third glass no fire because inside glass has only carbon dioxide, no oxygen help burn it be no fire.
2.2 Interpretation of results
3.0 Conclusion
Light help that plants release oxygen come out.
4.0 Recommendation
Light is necessary for photosynthesis.
