Which illustrates the correct order of the stages of photosynthesis?

Question 4 options:

At the left-hand side of the image, a stack of disc-like objects shows one arrow labeled water and a second arrow labeled ADP and NADP plus entering the bottom of the stack. Oxygen labels an arrow leaving the top of the stack. ATP and NADPH label an arrow exiting the side of the stack which points toward the middle image. The middle image shows the label energy from sunlight with two arrows pointing toward a stack of disc-like objects. At the right-hand side of the image, carbon dioxide is the label that sits above an arrow that enters a circular process. Glucose labels and arrow exiting the bottom of that circular process.

At the left-hand side of the image, carbon dioxide is the label that sits above and arrow that enters a circular process. Glucose labels and arrow exiting the bottom of that circular process. The middle of the image shows the label energy from sunlight with two arrows pointing toward a stack of disc-like objects. At the right-hand side of the image, a stack of disc-like objects shows one arrow labeled water and a second arrow labeled ADP and NADP plus entering the bottom of the stack. Oxygen labels an arrow leaving the top of the stack. ATP and NADPH label an arrow exiting the side of the stack which points outward, away from the stack of disc-like objects.

The left-hand side of the image shows the label energy from sunlight with two arrows pointing toward a stack of disc-like objects. At the middle of the image, a stack of disc-like objects shows one arrow labeled water and a second arrow labeled ADP and NADP plus entering the bottom of the stack. Oxygen labels an arrow leaving the top of the stack. ATP and NADPH label an arrow exiting the side of the stack which points toward the right hand image . At the right-hand side of the image, carbon dioxide is the label that sits above and arrow that enters a circular process. Glucose labels and arrow exiting the bottom of that circular process.

The correct order of stages in photosynthesis is as follows:

1. **Light-dependent reactions**: These occur in the thylakoid membranes of the chloroplasts where light energy is captured and converted into chemical energy in the form of ATP and NADPH. Water is split during this process, releasing oxygen as a byproduct.

2. **Calvin cycle (Light-independent reactions)**: This takes place in the stroma of the chloroplasts. Here, carbon dioxide is fixed and ultimately used to produce glucose, utilizing the ATP and NADPH generated in the light-dependent reactions.

Based on this understanding, the third option describes the stages correctly:

- "The left-hand side of the image shows the label energy from sunlight with two arrows pointing toward a stack of disc-like objects." (This represents the light-dependent reactions where sunlight energy is captured.)
- "At the middle of the image, a stack of disc-like objects shows one arrow labeled water and a second arrow labeled ADP and NADP plus entering the bottom of the stack." (This supports the light-dependent reactions.)
- "Oxygen labels an arrow leaving the top of the stack." (Oxygen is released as a byproduct.)
- "ATP and NADPH label an arrow exiting the side of the stack which points toward the right-hand image." (These are the products used in the Calvin cycle.)
- "At the right-hand side of the image, carbon dioxide is the label that sits above and arrow that enters a circular process." (This represents the Calvin cycle.)
- "Glucose labels an arrow exiting the bottom of that circular process." (This is the output of the Calvin cycle.)

So the third option illustrates the correct order of the stages of photosynthesis.
