Cell Structure, Organization & Cell Division
Solution
Which of the following substances is contained in chloroplasts?
A
Starch
B
Sugar
C
Glycogen
D
Dextrin
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
Chloroplasts are the primary sites of photosynthesis in plant cells where glucose is generated. This glucose is rapidly converted and stored inside the stroma of the chloroplast as insoluble starch granules for temporary energy storage.
Dextrin is an intermediate breakdown product or derivative of starch, rather than a primary substance stored naturally within healthy chloroplasts.Hence, starch appears to be the most appropriate answer.
