Revolt · Accepted Answer

B – stroma

Question 3

Identify structure C.

Revolt · Accepted Answer

C – granum

Question 4

Identify structure D.

Revolt · Accepted Answer

D – thylakoid

Question 5

For each of the following processes, identify the part of the chloroplast in which it takes place. Light-dependent reactions Light-independent reactions Sun’s energy absorbed Sugars produced

Revolt · Accepted Answer

thylakoids; Selection 1: thylakoids; Selection 2: stroma; Selection 3: thylakoids; Selection 4: stroma

Question 6

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

In the process of photosynthesis, plants use energy from sunlight to convert carbon dioxide and water into glucose (sugar) and oxygen. Sunlight is the energy source that drives the chemical reactions, and this energy is ultimately stored within the chemical bonds of the glucose molecule produced.

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

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 a completely different and likely uninhabitable planet for most modern life forms. Because photosynthesis is the primary process that releases oxygen into the atmosphere, there would be very little oxygen for aerobic organisms to breathe. Furthermore, plants serve as the foundation of almost every food chain; without them, there would be no food for herbivores or the carnivores that eat them. Additionally, we would lack essential materials derived from plants, such as timber for building, fibers for clothing, many medicines, and even fossil fuels, which are formed from the remains of prehistoric photosynthetic organisms.

Question 9

Light-independent reactions

Revolt · Accepted Answer

stroma

Question 10

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.
