Question

Review this set-up for photosynthesis. Select ALL of the primary limiting factors that impact the rate of photosynthesis for this lab set-up.



a
collected oxygen volume
b
dissolved glucose concentration
c
dissolved carbon dioxide concentration
d
light intensity

Answer 1

In the context of photosynthesis, the primary limiting factors that impact the rate of this process include:

- **c. dissolved carbon dioxide concentration**: Carbon dioxide is a crucial reactant in the photosynthesis process, and its availability can limit the rate at which photosynthesis occurs.

- **d. light intensity**: Light is essential for photosynthesis, and the rate of photosynthesis typically increases with light intensity up to a certain point.

The other options, **a. collected oxygen volume** and **b. dissolved glucose concentration**, do not directly limit the rate of photosynthesis. While oxygen is a product of photosynthesis and glucose is a product of the entire process, the volume of oxygen collected does not limit the process, and the concentration of glucose is more a product than a limiting factor in the actual photosynthesis reaction.

So the correct answers are:

- **c. dissolved carbon dioxide concentration**
- **d. light intensity**
