Study Notes
A Plant’s Raw Materials
-
The optimal ranges for each factor to produce the highest amount of oxygen bubbles are:
- Water: Between 10-15mL
- Light: Between 10-15 Watts
- CO2: Between 10-15 ppm
- Temperature: Between 20-30°C
Oxygen Bubbles: A Reliable Indicator of Photosynthetic Activity
- Increasing the amount of water, light, CO2, and temperature initially results in an increase in the production of oxygen bubbles.
- There is a point where increasing these factors no longer increases oxygen production.
- This point seems to be around 10-15 or 11-15 for each factor and the number of bubbles seems to decrease after this point.
- This indicates that oxygen bubbles are a reliable indicator of photosynthetic activity up to a certain point.
- However, increasing these factors beyond that point will result in lower oxygen production.
Reactants and Products of Photosynthesis
- The reactants in photosynthesis are carbon dioxide (CO2) and water (H2O).
- The products of photosynthesis are sugar (glucose) and oxygen (O2).
Why Plants Need Sugar
- Plants produce sugar through photosynthesis to use for energy (ATP), growth, and reproduction.
- Sugar is the primary source of energy for plants.
Transforming Sugar
- Plants transform sugar into proteins and other necessary substances through a process called protein synthesis.
- This process combines amino acids, which are obtained from the breakdown of sugar, to create proteins.
- ** Similar to how animals digest food, plants need to break down the glucose they produce.**
Tommy’s Tomatoes
- Red and blue light are the best colors for plant growth.
- The plant in red light produced the most growth after 100 days, with a total of 36 cm.
- The plant in blue light produced the second most growth after 100 days, with a total of 38 cm.
- The plant in natural white light had 29 cm of total growth
- The plant in violet light had 35 cm of total growth
- The plant in yellow light had 22 cm of total growth
- The plant in orange light had 24 cm of total growth
- This suggests that different wavelengths of light have different effects on plant growth.
- If you were to repeat this experiment, you could increase the light intensity and make sure that the amount of water, CO2, and temperature were also optimized to give the plants the best conditions for growth.
- This would allow for increased outputs of photosynthesis.
