Question

Storage bodies, pyrenoids in the chloroplast contain

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: Composition of Pyrenoids
	**Related Topics**: Chloroplast, Photosynthesis, Plant Cell Structure
	**Prerequisites**: Basic knowledge of cell organelles and their functions.
## SOLUTION PATHWAY
**Given Information**:
	The question asks about the composition of pyrenoids within chloroplasts.
	Correct answer is given as protein and starch
**Method & Steps**:
	1. Recall the composition of pyrenoids: Pyrenoids are known to primarily contain protein and act as centers for starch synthesis
	Reasoning: Pyrenoids are specialized structures within chloroplasts of algae and certain plants involved in carbon fixation.
	2.  Match the known composition to the correct option.

Result: Option A correctly identifies the composition of pyrenoids as protein and starch.
 ## OPTION ANALYSIS
[A] ✓: Pyrenoids primarily contain protein and starch. Protein acts as the scaffolding and enzymes for starch production, while starch is the storage carbohydrate produced in the chloroplast.
[B] :x: While carbohydrates are involved in photosynthesis, the primary storage carbohydrate in pyrenoids is starch, not a general carbohydrate. Also, this option is too broad and doesn't specify the exact form of carbohydrate.
[C] :x: This option is incorrect because it includes polysaccharide as a broad category, starch is a specific polysaccharide and protein is the second component.
[D] :x: Lipids are not a significant component of pyrenoids. They are primarily involved in membrane structure and energy storage in other parts of the cell.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Confusing with other storage structures]: [Distinguish pyrenoids from other storage bodies like vacuoles.]
		2.[Overgeneralization of carbohydrates]: [Remember that starch is the specific carbohydrate stored in pyrenoids.]
	**Quick Tips**:
		1.[Think 'starch-producing protein matrix']: [Use the phrase to remember the composition of pyrenoids]
		2.[Relate to Photosynthesis]: [Recall pyrenoids are involved in carbon fixation (starch synthesis)]
