Plants differ from animals in having :

Options

A. definite lifespan
B. localized growth
C. indefinite lifespan
D. localized growth and indefinite lifespan

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how plants differ from animals. We need to identify a characteristic that is unique to plants.

2. **Analyzing the Options**: We have four options to consider:
- A) Definite lifespan
- B) Localized growth
- C) Indefinite lifespan
- D) Both localized growth and indefinite lifespan

3. **Evaluating Option A (Definite lifespan)**:
- Both plants and animals have a definite lifespan. For example, a banyan tree can live for about 1000 years, while humans have an average lifespan of around 79 years. Therefore, this option is incorrect.

4. **Evaluating Option B (Localized growth)**:
- Plants exhibit localized growth, meaning growth occurs in specific areas (like meristematic tissues). In contrast, animals show diffuse growth, where growth occurs throughout the body. This characteristic is indeed a difference between plants and animals, making this option correct.

5. **Evaluating Option C (Indefinite lifespan)**:
- This option suggests that plants have an indefinite lifespan while animals have a definite lifespan. This is incorrect because plants also have a definite lifespan, as discussed earlier.

6. **Evaluating Option D (Both localized growth and indefinite lifespan)**:
- While the part about localized growth is correct, the claim about indefinite lifespan is incorrect. Therefore, this option is also wrong.

7. **Conclusion**: The correct answer is Option B, which states that plants differ from animals in having localized growth.
