Cell division occurs throughout the body in animals. It occurs in localized ___ regions in higher plants.

Options

A. meristematic
B. young
C. mature
D. differentiated

Answer

**Step-by-Step Solution:**

1. **Understanding Cell Division in Animals:**
- In animals, cell division occurs throughout the body. This means that new cells are formed in various tissues and organs, allowing for growth, repair, and maintenance of the body.

2. **Cell Division in Higher Plants:**
- In contrast to animals, cell division in higher plants is not uniform throughout the entire organism. Instead, it occurs in specific, localized regions.

3. **Identifying Localized Regions in Plants:**
- The regions where cell division occurs in higher plants are known as meristematic regions. These regions contain meristematic tissue, which is responsible for the growth of the plant.

4. **Types of Meristematic Tissue:**
- There are three main types of meristematic tissue:
- **Apical Meristem:** Located at the tips of roots and shoots, responsible for vertical growth (height).
- **Lateral Meristem:** Found along the sides of stems and roots, responsible for growth in thickness (width).
- **Intercalary Meristem:** Located between the nodes (internodes) of stems, contributing to growth in length.

5. **Conclusion:**
- Therefore, the correct answer to the question is that cell division occurs in localized **meristematic** regions in higher plants.

**Final Answer:**
Cell division occurs throughout the body in animals. It occurs in localized **meristematic** regions in higher plants.
