Plants differ from animals in having

Options

A. Definite lifespan
B. Localized growth
C. Indefinite growth
D. Localized growth and indefinite lifespan

Answer

To solve the question "Plants differ from animals in having," we need to analyze the provided options and identify the key differences between plants and animals. Here’s a step-by-step breakdown:

### Step 1: Understand the Options
The options given are:
1. Definite lifespan
2. Localized growth
3. Indefinite growth
4. Localized growth with indefinite lifespan

### Step 2: Analyze Each Option
- **Definite Lifespan**: Both plants and animals have a definite lifespan. While plants can live for a long time, they eventually die, just like animals. Thus, this option does not highlight a difference.

- **Localized Growth**: Plants exhibit localized growth, meaning they continue to grow in specific areas (meristematic zones) throughout their lives. In contrast, animals generally stop growing after reaching maturity. This is a significant difference.

- **Indefinite Growth**: While plants can grow indefinitely in certain conditions, this term can be misleading. Not all parts of the plant grow indefinitely; only specific zones do. Therefore, this option is not entirely accurate as a distinguishing feature.

- **Localized Growth with Indefinite Lifespan**: This option is incorrect because plants do not have an indefinite lifespan; they do eventually die.

### Step 3: Conclusion
After analyzing all the options, the most accurate distinction is that plants have **localized growth**, which allows them to continue growing in specific areas throughout their lives, unlike animals that stop growing after a certain age. Therefore, the correct answer is:

**Plants differ from animals in having localized growth.**
