Question

Under which environmental condition would bulliform cells be most likely to cause a grass leaf to roll inwards?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [D]
## CONCEPT FRAMEWORK
	**Primary Concept**: Bulliform cells and their role in plant water regulation
	**Related Topics**: Plant physiology, leaf structure, water conservation mechanisms
	**Prerequisites**: Understanding of plant adaptations to environmental stressors
## SOLUTION PATHWAY
**Given Information**:
		- Bulliform cells are specialized cells in grass leaves that help in water regulation.
		- The question explores the conditions that lead to leaf rolling as a response to environmental stress.
**Method & Steps**:
	1.	Identify the role of bulliform cells in response to environmental conditions.
		Reasoning: Bulliform cells can collapse to reduce leaf surface area, minimizing water loss.
		Formula/Rule: None applicable directly, but it relates to the concept of transpiration and water loss.
	2.	Consider the environmental conditions listed in the options.
		Working: High humidity would lead to less need for water conservation, while low light and cold temperatures do not primarily induce rolling.
		Key Point: Hot, dry conditions create a significant moisture deficit.
	3.	Determine the most likely condition that would trigger bulliform cells to respond.
		Result: Hot, dry conditions would lead to the rolling of leaves to conserve water.
		Verification: This aligns with plant physiological responses to drought stress.
## OPTION ANALYSIS
[A] :x: High humidity does not induce leaf rolling as it promotes water availability.
[B] :x: Low light intensity does not directly affect the need for water conservation in this context.
[C] :x: Cold temperatures do not typically cause leaf rolling in grasses.
[D] ✓: Hot, dry conditions lead to water loss and the need for leaf rolling to minimize transpiration.
## LEARNING AIDS
	**Common Mistakes**:
		1. Misunderstanding the function of bulliform cells: Remember they primarily respond to water stress.
		2. Confusing environmental conditions: Ensure clarity on how each condition affects plant physiology.
	**Quick Tips**:
		1. Associate bulliform cells with drought stress responses to remember their function.
		2. Recall that rolling is a mechanism for reducing surface area exposed to the atmosphere, thereby conserving moisture.
