Meristematic activities are best seen in

Options

A. Fruit
B. Root and shoot apices
C. At leaf tips
D. All of these

Answer

To solve the question "Meristematic activities are best seen in", we need to understand what meristematic activity is and where it occurs in plants. Here’s a step-by-step breakdown of the solution:

### Step 1: Define Meristematic Activity
Meristematic activity refers to the growth process in plants that involves the division of undifferentiated cells known as meristematic cells. These cells are capable of continuous division and contribute to the growth of the plant.

**Hint:** Remember that meristematic cells are undifferentiated and can divide to form new tissues.

### Step 2: Identify Locations of Meristematic Activity
Meristematic tissues are primarily located at specific regions of the plant:
- **Apical Meristems:** These are found at the tips of roots and shoots. They are responsible for the primary growth of the plant.
- **Lateral Meristems:** These contribute to secondary growth, but they are not the focus of this question.

**Hint:** Focus on the tips of the plant where growth occurs.

### Step 3: Analyze the Options
The question provides several options:
1. Fruit
2. Root and shoot apices
3. Leaf tips
4. All of the above

From our understanding:
- The root and shoot apices are where meristematic activity is most active.
- While leaf tips may have some meristematic activity, it is not as significant as that at the root and shoot apices.
- Fruits develop from the shoot apical meristem, but they are not the primary sites of meristematic activity.

**Hint:** Consider which of the options directly relates to the primary sites of growth.

### Step 4: Select the Correct Answer
Based on the analysis, the best answer is "root and shoot apices" because these are the primary locations where meristematic activity is most evident.

**Final Answer:** Meristematic activities are best seen in root and shoot apices.
