Which describes the stroma within a chloroplast?
Understand the Problem
The question is asking for a description of the stroma within a chloroplast, specifically identifying which option correctly defines it based on the roles and locations of chloroplast components.
Answer
Fluid-filled space in chloroplasts surrounding thylakoids, site of Calvin cycle.
The stroma within a chloroplast is the fluid-filled space surrounding the thylakoids where the Calvin cycle occurs, converting carbon dioxide into glucose.
Answer for screen readers
The stroma within a chloroplast is the fluid-filled space surrounding the thylakoids where the Calvin cycle occurs, converting carbon dioxide into glucose.
More Information
The stroma is comparable in function to the mitochondrial matrix, hosting the chloroplast's genetic system and various metabolic activities.
Tips
A common mistake is confusing the stroma with the thylakoid space, which is inside the thylakoids where the light-dependent reactions take place.
