Plants photosynthesis co2

• What role does carbon play in photosynthesis?

  Photosynthesis is directly related to the carbon cycle, as plants need carbon to sustain themselves. Plants remove carbon from the atmosphere (in the form of carbon dioxide) and release oxygen as a byproduct. On a side note, humans do the exact opposite, they require oxygen for cellular respiration, and as a byproduct they release carbon dioxide.

• How does CO2 affect the rate of photosynthesis?

  Why does CO2 increase photosynthesis? Increased photosynthesis under e [CO 2] mainly occurs due to an increase in ribulose-1,5-bisphosphate (RuBP) carboxylase/oxygenase (Rubisco) activity. Elevated [CO 2] increases the availability of carbon in leaves causing greater Rubisco activity and higher rates of photosynthesis.

• What happens to carbon dioxide during photosynthesis?

  During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

• What is the role of carbon dioxide in photosynthesis?

  What role does carbon dioxide play in photosynthesis? Answer. Carbon dioxide provides the carbon that the plant uses to produce glucose. Carbon dioxide is combined with water using the energy from sunlight. The carbon in glucose is not only used in cellular respiration to make ATP, but actually makes up most of the plants.

  Plants and the Short-term Carbon Cycle:Part 1 (30 minutes) Ask students to describe the role of plants in the short-term carbon cycle. Review the chemical equations for photosynthesis and respiration highlighting oxygen and carbon dioxide in each equation. Photosynthesis: 6CO + 6H 2O → C 2 6H 12O 6+ 6O 2.

  In photosynthesis, plants use carbon dioxide from air and water in the soil with the sun’s energy to generate photosynthates (sugar) releasing oxygen as a byproduct. [Figure 1] Figure 1. Photosynthesis Photosynthesis literally means to put together with light. It occurs only in the chloroplasts,

  Plants are the central link in this transformation, convert- ing inorganic carbon dioxide (C02) in the atmosphere to adapts. This increase in photosynthetic rate may account in part for the ‘ disappearance’ of an estimated 1.8 gigatons of organic carbon in the biosphere by photosynthesis.

  The overall stoichiometry of photosynthesis has one mole (or molecule) of oxygen is produced per mole of CO2 that is fixed or assimilated. This allows us to measure the apparent photosynthetic rate by assessing the amount of O2 that a leaf produces or the amount of CO2 that is taken up by a leaf.
