Elodea leaf experiment

Explanation:

1. What did you observe on the elodea leaves

Gas bubbles are formed on the elodea leaves

2. What substance accumulated in the leaves

Oxygen is accumulated in the leaves

3. How do you know what it is

The end product of photosynthesis reactions are sugar and oxygen. Sugar is a solid and the released gas should be oxygen

4. Should the substance be considered a waste product explain

Oxygen is released during photosynthesis and is considered as a by-product and a waste product of photosynthesis because plants need oxygen for respiration only and not for photosynthesis

5. What reaction is taking place

Photosynthesis light dependent reaction converts the solar energy into chemical energy .

6. Where does the reaction take place in the plant what organelle

Light reaction takes place in the chloroplasts. This occurs in the stacked thyllakoids which contains the chlorophyll pigments which aid in photosynthesis

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
