B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
	**Primary Concept**: Understanding the basic requirements for life and growth in organisms.
	**Related Topics**: Cellular respiration, photosynthesis, nutrient uptake, environmental influences on organisms.
	**Prerequisites**: Basic knowledge of biology, plant physiology, and environmental science.
## SOLUTION PATHWAY
**Given Information**:
	Four statements regarding the requirements for growth and survival of organisms.
	Need to identify the correct statements.
**Method & Steps**:
	1. Analyze each statement individually.
		Reasoning: Determine if the statement is factually correct based on biological principles.
	2. Identify all correct statements.
	3. Select the option containing only correct statements.
		
	**Step-by-step Analysis of Statements**:
		Statement I: ${O_2}$ helps in releasing metabolic energy, which is essential for growth.
			Working: Oxygen is essential for cellular respiration, which releases energy in the form of ATP.
			Key Point: This is a fundamental process for growth and survival.
			Result: Correct
		Statement II: Nutrients are required by plants for the synthesis of protoplasm.
			Working: Protoplasm is the living content of a cell. Nutrients provide the building blocks for this.
			Key Point: Nutrients are essential for all cellular components.
			Result: Correct
		Statement III: Change in temperature could be the detrimental for the survival of an organism.
			Working: Extreme temperatures can denature enzymes and disrupt cellular processes.
			Key Point: Organisms have optimal temperature ranges for survival.
			Result: Correct
		Statement IV: Light and gravity don’t affect the stages of growth.
			Working: Light is necessary for photosynthesis, and gravity influences root growth (gravitropism).
			Key Point: Both light and gravity are important environmental factors that influence plant growth and development.
			Result: Incorrect
	4. Identify the option containing correct statement I, II and III.
		Result: Option B is the correct option
 ## OPTION ANALYSIS
[A] :x: Incorrect because it includes the incorrect statement IV.
[B] ✓: Correct, it includes only the correct statements I, II, and III.
[C] :x: Incorrect because it includes the incorrect statement IV and does not include the correct statement II.
[D] :x: Incorrect because it includes the incorrect statement IV and does not include the correct statement III.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Error 1: Confusing the role of light and gravity in plant growth.
			How to avoid: Remember that light is essential for photosynthesis, and gravity influences root growth.
		2. Error 2: Misunderstanding the importance of nutrients for protoplasm synthesis.
			How to avoid: Understand that protoplasm is made of biomolecules, which come from nutrients.
	**Quick Tips**:
		1. Helpful shortcut: When analyzing statements, consider the basic biological processes they relate to.
		2. Memory aid: Remember that oxygen, nutrients, and a suitable environment are essential for life and growth.
