The cells of meristems have

Options

A. young immature dividing cells with large conspicuous nuclei and no intercellular spaces
B. large vacuoles
C. abundant cell inclusions
D. all of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Meristematic Tissue**:
- Meristematic tissues are composed of cells that are actively dividing. These cells are responsible for the growth of plants.

2. **Characteristics of Meristematic Cells**:
- **Young and Immature**: The cells of meristems are young and not yet differentiated into specialized cells. They are in a constant state of division.
- **Dense Cytoplasm**: These cells have a dense cytoplasm which indicates high metabolic activity.
- **Prominent Nuclei**: Meristematic cells have large and conspicuous nuclei, which are essential for the process of cell division.
- **Less Intercellular Space**: There are minimal intercellular spaces in meristematic tissues, allowing for efficient cell division and growth.
- **More Organelles**: Due to their active nature, these cells contain a higher number of organelles such as mitochondria and endoplasmic reticulum to support their metabolic functions.
- **Vacuoles**: While they may have vacuoles, they are generally smaller compared to mature cells, as these cells are still in the process of division.

3. **Evaluating the Options**:
- **Option 1**: Young cells with conspicuous nuclei and less intercellular spaces – This is correct.
- **Option 2**: Large vacuoles – This is partially correct as they may have smaller vacuoles compared to mature cells.
- **Option 3**: Abundant cell inclusions – This is generally not a characteristic of meristematic cells, as they focus more on division rather than storage.
- **Option 4**: All of the above features – Given that the first two options are correct, this option is also correct.

4. **Conclusion**:
- The cells of meristems exhibit characteristics such as being young, having dense cytoplasm, prominent nuclei, and minimal intercellular spaces. Therefore, the correct answer is that they possess all of the mentioned features.

**Final Answer**: The cells of meristems have all of the following features.
