Question

У процесі фотосинтезу за один світловий день (12 год) рослина помідору вбирає 132 г СО2. Яка маса глюкози ( в грамах) може утворитися в її листках протягом 10 днів?

Answer 1

The Process of Photosynthesis

Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose (a type of sugar) and oxygen. This process occurs in the chloroplasts of plant cells, specifically in the green pigment called chlorophyll. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose and oxygen.

Calculation of Glucose Formation

To calculate the mass of glucose that can be formed in the leaves of a tomato plant over a period of 10 days, we need to consider the amount of carbon dioxide absorbed by the plant during photosynthesis.

Given that the tomato plant absorbs 132 g of carbon dioxide in one light day (12 hours), we can calculate the amount of carbon dioxide absorbed in 10 days as follows:

132 g CO2/day * 10 days = 1320 g CO2

Since the molecular formula of glucose is C6H12O6, we can calculate the molar mass of glucose as follows:

6 carbon atoms * 12.01 g/mol = 72.06 g/mol 12 hydrogen atoms * 1.01 g/mol = 12.12 g/mol 6 oxygen atoms * 16.00 g/mol = 96.00 g/mol

Total molar mass of glucose = 72.06 g/mol + 12.12 g/mol + 96.00 g/mol = 180.18 g/mol

To calculate the mass of glucose formed, we need to determine the ratio of carbon dioxide to glucose in the photosynthesis reaction. From the balanced equation of photosynthesis, we know that for every 6 molecules of carbon dioxide, 1 molecule of glucose is formed.

Therefore, the mass of glucose formed can be calculated as follows:

(1320 g CO2) / (6 * 44.01 g CO2/mol) * (1 mol glucose / 6 mol CO2) * (180.18 g glucose/mol) = 660 g glucose

Therefore, the mass of glucose that can be formed in the leaves of the tomato plant over a period of 10 days is 660 grams.
