In plant, mitotic cell division is seen in the -

Answer

**Step-by-Step Solution:**

1. **Understanding Mitotic Cell Division**:
- Mitotic cell division is a process where a single cell divides to produce two identical daughter cells. This type of division maintains the same number of chromosomes in both the parent and daughter cells, hence it is often referred to as equational division.

2. **Occurrence in Plants**:
- In plants, mitosis can occur in both haploid (n) and diploid (2n) cells. This is different from animals, where mitosis primarily occurs in diploid somatic cells.

3. **Alternation of Generations**:
- Plants exhibit a life cycle known as alternation of generations, which includes both a haploid gametophyte stage and a diploid sporophyte stage. This means that mitosis is necessary in both stages.

4. **Example of Mitosis in Plants**:
- For instance, in bryophytes (a group of non-vascular plants), the gametophyte is produced from the mitotic division of spores. Spores are haploid and undergo mitosis to develop into the gametophyte.

5. **Conclusion**:
- Therefore, in plants, mitotic cell division is seen in both haploid and diploid cells.

**Final Answer**: In plants, mitotic cell division is seen in both haploid and diploid cells.
