Tapetal cells are characterised by

Options

A. Mitotic division
B. Meiotic division
C. Endomitosis
D. Endomitosis as well as endopolyploidy

Explanation

**Step-by-Step Solution:**

1. **Understanding Tapetal Cells**: Tapetal cells are specialized cells found in the anther of flowering plants. They are part of the innermost layer of the anther wall, known as the tapetum.

2. **Function of Tapetal Cells**: The primary role of tapetal cells is to provide nourishment to the developing pollen grains. They are crucial for the development of male gametes in plants.

3. **Characteristics of Tapetal Cells**: Tapetal cells are characterized by:
- **Multinucleation**: This means that the tapetal cells contain multiple nuclei. This is a result of specific cellular processes.
- **Endomitosis**: This is a process where the chromosomes replicate without the cell undergoing division, leading to an increase in the number of nuclei within the cell.
- **Endopolyploidy**: Similar to endomitosis, this process involves the replication of the genome, resulting in cells with multiple sets of chromosomes without cell division.

4. **Conclusion**: Therefore, tapetal cells are characterized by their multinucleated nature, which arises from processes like endomitosis and endopolyploidy, allowing them to efficiently support pollen development.
