Understanding Growth Concepts
In the context of plant biology, it is crucial to differentiate between absolute growth and relative growth. Let's break down the statements given in the question.
1. Absolute Growth vs. Relative Growth
- Absolute Growth refers to the actual increase in size or mass of an organism over a specific time period.
- Relative Growth is the increase in size or mass relative to the original size or mass, often expressed as a percentage.
2. Analysis of Statements
- Statement (1): "Two leaves having different relative growth can have the same absolute growth."
- This is correct.
- For example, Leaf A may grow 10 grams while Leaf B grows 5 grams, but if Leaf A was initially 100 grams (10% growth) and Leaf B was 50 grams (10% growth), they have different relative growth rates but the same absolute increase.
- Statement (2): "Two leaves having different absolute growth can have the same relative growth."
- This is also correct.
- For instance, Leaf A could increase from 100 grams to 120 grams (20% growth), while Leaf B increases from 200 grams to 240 grams (also 20% growth). They have different absolute growth (20 grams vs. 40 grams) but share the same relative growth rate.
Conclusion
Given the analysis, both statements are indeed correct.
- Correct Answer: Option 'C' – both statements are correct.
Understanding these concepts is vital for interpreting growth patterns in biological systems, especially in the context of exams like NEET.
