Question

Osmoregulation is maintained by?

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Osmoregulation
	**Related Topics**: Cell membranes, Transport across membranes, Plant cell structure
	**Prerequisites**: Basic knowledge of cell biology and membrane function.
## SOLUTION PATHWAY
**Given Information**:
	Question asks about structures involved in maintaining osmoregulation.
	Options are cell membrane components.
**Method & Steps**:
	1. Identify the role of each membrane: 
		Reasoning: Osmoregulation involves regulating water and solute concentration.
	2. Analyze options:
		Working: Plasma membrane controls entry and exit of substances, including water and solutes. Tonoplast regulates solute concentration within the vacuole, impacting osmotic balance.
	3. Final step:
		Result: Both plasma membrane and tonoplast are involved in osmoregulation.
		Verification: Option D indicates 1 and 3 are correct, which are plasma membrane and tonoplast.
 ## OPTION ANALYSIS
[A] :x: Plasma membrane alone is not the only structure involved in osmoregulation.
[B] :x: Nuclear membrane regulates transport in/out of nucleus, not osmoregulation.
[C] :x: Tonoplast is also involved in osmoregulation, so this is incomplete answer.
[D] ✓: Both plasma membrane and tonoplast are involved in osmoregulation.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Thinking only about the plasma membrane: Remember that plant cells have a large vacuole and tonoplast that also play a role in osmoregulation.
		2. Confusing membranes: Understand the distinct functions of different cell membranes.
	**Quick Tips**:
		1.Think of osmosis as water movement towards areas with higher solute concentration. Both plasma membrane and tonoplast control solute distribution.
		2. Recall the function of the vacuole in plant cells as a storage and osmoregulatory organelle.
