Question

What tissue constitutes the pith in a dicot stem?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant Anatomy, specifically the internal structure of dicot stems.
	**Related Topics**: Ground tissue, parenchyma cells, collenchyma, sclerenchyma, xylem, phloem.
	**Prerequisites**: Basic understanding of plant tissues and their functions.
## SOLUTION PATHWAY
**Given Information**:
	The question asks about the tissue composition of the pith in a dicot stem.
	The options are: Collenchyma, Sclerenchyma, Xylem, and Parenchyma.
**Method & Steps**:
	1. Understand the structure of a dicot stem: Dicot stems have a central region called the pith, surrounded by vascular bundles (xylem and phloem) and a cortex.
		Reasoning: The pith is typically a storage region in the stem. 
	2. Identify the tissue type that is commonly found in storage regions: Parenchyma cells are the primary cells involved in storage in plants.
		Working: Parenchyma cells are thin-walled, living cells that are responsible for storage, photosynthesis, and other metabolic functions.  They are the most abundant cell type in plants.
		Key Point: While other tissues might be present in small amounts in the pith, parenchyma is the dominant tissue type.
	3. Select the correct option:
		Result: Parenchyma is the tissue that constitutes the pith in a dicot stem.
		Verification: This aligns with the typical structure and function of dicot stems.
## OPTION ANALYSIS
A :x: Collenchyma provides support to young stems, but it's not the primary tissue in the pith.
B :x: Sclerenchyma provides structural support through sclereids and fibers, but is not the main component of the pith.
C :x: Xylem is involved in water transport and is located in the vascular bundles, not the pith.
D ✓: Parenchyma is the primary tissue of the pith, fulfilling its storage function.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing pith with cortex: The cortex is the region outside the vascular bundles, while the pith is the central region.
			How to avoid: Carefully study the cross-section diagrams of dicot stems.
		2.  Assuming only one tissue type is present: The pith might contain small amounts of other tissues, but parenchyma is the predominant tissue.
			How to avoid: Focus on the main function of the pith (storage) and the cell type best suited for that function.
	**Quick Tips**:
		1. Remember that parenchyma is the 'general purpose' tissue in plants, involved in various functions, including storage.
		2. Use mnemonics or diagrams to remember the arrangement of tissues in a dicot stem.
