✔ stroma

Question 5

Answer the following question about the generalized photosynthesis equation below:6CO2 + 6H2O C6H12O6 + 6O2Describe in words what occurs during the process represented by the photosynthesis equation. Include the importance of sunlight

Revolt · Accepted Answer

During photosynthesis, plants use sunlight to provide the energy needed to combine carbon dioxide and water in a series of chemical reactions. The process produces glucose, a sugar that stores the energy from sunlight and serves as food for the plant, and oxygen gas.

Question 6

Which details did you include in your description of the photosynthesis equation? Check all that apply.

Revolt · Accepted Answer

Carbon dioxide and water are combined in a series of reactions.; Sunlight provides energy for the reactions.; The end result of photosynthesis is the production of sugars (glucose, a food) and oxygen (a gas).; The energy from sunlight is stored in the glucose.

Question 7

Answer the following questions about the generalized photosynthesis equation:6CO2 + 6H2O C6H12O6 + 6O2What are the reactants of photosynthesis? Check all that apply.

Revolt · Accepted Answer

carbon dioxide; water

Question 8

What are the products of photosynthesis? Check all that apply.

Revolt · Accepted Answer

glucose; oxygen

Question 9

Write a paragraph describing how Earth would be different if photosynthetic plants had not evolved.

Revolt · Accepted Answer

If photosynthetic plants had not evolved, Earth would be very different. There would be no trees or flowering plants, and most organisms would have no food because plants form the base of most food chains. The atmosphere would contain little or no oxygen, so most animals and humans could not survive. People would also lack many plant-based products, including building materials, medicines, fuels, and fibers. Fossil fuels would not have formed because they developed from ancient plant and organism remains.

Question 10

Which ideas did your answer contain? Check all that apply.

Revolt · Accepted Answer

no food for organisms; no oxygen in the atmosphere; no trees or flowering plants; no products based on trees or plants (building materials, medicines, fuels, fibers); no fossil fuels
