Question

Which of the following is responsible for the radial growth of plants?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [Option C]
## CONCEPT FRAMEWORK
	**Primary Concept**: Lateral meristem and its role in plant growth
	**Related Topics**: Plant anatomy, meristems, growth patterns in plants
	**Prerequisites**: Understanding of plant growth and development
## SOLUTION PATHWAY
**Given Information**:
		- Options provided: Apical meristem, Intercalary meristem, Lateral meristem, Parenchyma
		- Focus on growth types in plants
**Method & Steps**:
	1. Identify the type of meristem involved in radial growth.
		Reasoning: Radial growth refers to the increase in the girth of the plant, not the height.
		Formula/Rule: Radial growth is primarily due to lateral meristems.
	2. Analyze the options based on their functions.
		Working: 
		- Apical meristem is responsible for vertical growth (height).
		- Intercalary meristem contributes to elongation at internodes.
		- Lateral meristem is responsible for thickening.
		- Parenchyma is a type of tissue but does not directly contribute to meristematic growth.
		Key Point: Lateral meristem includes the vascular cambium and cork cambium, both of which facilitate radial growth.
	3. Conclude with the correct option.
		Result: The option corresponding to lateral meristem is correct.
		Verification: Lateral meristem indeed contributes to the radial growth of stems and roots, confirming option C.
 ## OPTION ANALYSIS
[A] :x: Apical meristem is responsible for vertical growth, not radial growth.
[B] :x: Intercalary meristem contributes to elongation at the internodes, not radial growth.
[C] ✓: Lateral meristem is responsible for radial growth, allowing for an increase in girth.
[D] :x: Parenchyma is a tissue type and does not function as a meristem.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing apical and lateral meristems: Remember, apical meristems grow plants taller, while lateral meristems grow them wider.
		2. Overlooking the role of intercalary meristem: It affects length but not girth.
	**Quick Tips**:
		1. Visualize plant growth: Think of trees getting wider rather than just taller as they age to remember lateral meristem functions.
		2. Recall that 'lateral' indicates side growth, which helps associate it with radial growth.
