Question

У процесі фотосинтезу за один світловий день (12 год) рослина цукрового буряка вбирає 44 г вуглекислого газу. Яка маса глюкози (теоретично) може утворитися і відкластися у його коренеплоді за 12 днів? Яка продуктивність фотосинтезу цієї рослини, якщо площа листкової поверхні становить 0,5 м2?

Answer 1

Ответ:

M(CO2) = 44 г*12 дней = 528 г

528 г                    х г  

6СO2 + 6H2O = C6H12O6 + 6O2

264 г                      180 г

х=360 г

360 г                   х г

2С6Н12О6 = С12Н22О11 + Н2О  

360 г                  342 г

х= 342 г

Ответ: 342 г

Calculation of Glucose Production in Sugar Beet

To calculate the theoretical mass of glucose that can be formed and stored in the root crop of a sugar beet plant during 12 days of photosynthesis, we need to consider the amount of carbon dioxide absorbed by the plant and the stoichiometry of glucose formation during photosynthesis.

Given: - Amount of carbon dioxide absorbed in one light day (12 hours): 44 g

During photosynthesis, glucose is formed from carbon dioxide and water according to the following balanced equation:

6 CO2 + 6 H2O → C6H12O6 + 6 O2

From this equation, we can see that for every 6 moles of carbon dioxide absorbed, 1 mole of glucose is produced. The molar mass of glucose is approximately 180 g/mol.

To calculate the theoretical mass of glucose produced, we can use the following steps:

1. Convert the mass of carbon dioxide absorbed to moles: - Moles of CO2 = Mass of CO2 / Molar mass of CO2 - Moles of CO2 = 44 g / 44.01 g/mol ≈ 1 mole

2. Determine the moles of glucose produced: - Moles of glucose = Moles of CO2 / 6 - Moles of glucose = 1 mole / 6 ≈ 0.167 moles

3. Calculate the mass of glucose produced: - Mass of glucose = Moles of glucose * Molar mass of glucose - Mass of glucose = 0.167 moles * 180 g/mol ≈ 30 g

Therefore, theoretically, approximately 30 grams of glucose can be formed and stored in the root crop of a sugar beet plant during 12 days of photosynthesis.

Calculation of Photosynthetic Productivity

To calculate the photosynthetic productivity of the sugar beet plant, we need to determine the amount of glucose produced per unit leaf surface area.

Given: - Leaf surface area: 0.5 m²

To calculate the photosynthetic productivity, we can use the following steps:

1. Convert the leaf surface area to square centimeters: - Leaf surface area = 0.5 m² * 10,000 cm²/m² = 5000 cm²

2. Calculate the mass of glucose produced per square centimeter of leaf surface area: - Glucose productivity = Mass of glucose / Leaf surface area - Glucose productivity = 30 g / 5000 cm² ≈ 0.006 g/cm²

Therefore, the photosynthetic productivity of the sugar beet plant is approximately 0.006 grams of glucose per square centimeter of leaf surface area.

Please note that these calculations are based on theoretical assumptions and may not represent the actual productivity of a sugar beet plant under real-world conditions.
