If carbon dioxide is completely removed from a plant’s environment, what would you expect to happen to the plant’s production of high-energy sugars (rate of photosynthesis)?

• Sugar production will likely increase

• The rate of sugar production will decrease

• Sugars will not be produced

• Fewer sugars will be produced at first, but then the plant will recover

Which statement best describes the difference between reactants and products?

• The reactants are the starting substances in a chemical reaction while products are the new substances formed as a result of a chemical reaction

• The products are the starting substances in a chemical reaction while reactants are the new substances formed as a result of a chemical reaction

• The reactants are glucose and oxygen and the products are carbon dioxide, water, and energy

• The reactants are what we get out of the reaction while the products are what is put into the reaction

Why are thylakoids necessary in the chloroplast?

• Thylakoids are where light independent reactions occur

• Thylakoids are where light dependent reactions occur

• The thylakoid is where carbon dioxide is absorbed

• A thylakoid is not necessary

Thylakoids are where the light independent reactions occur.

• Thylakoids are where the light independent reactions occur

• The thylakoid is where the carbon dioxide is absorbed into the chloroplast

• The thylakoid is where the light dependent reaction occurs

• Thylakoids are not necessary in a chloroplast

In summary, photosynthesis is a complex process by which plants and other photosynthetic organisms convert blank energy into chemical energy, providing the foundation for life on Earth. Which word best fills the blank?
