Describe any three factors controlling cell division.

Explanation

To describe three factors controlling cell division, we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Cell Size**:
- Cells must reach a certain size before they can divide. This is because the cell needs to have enough resources and organelles to support two daughter cells after division. Once a cell reaches its optimal size, it signals the onset of cell division.

2. **Nuclear-Cytoplasmic Ratio**:
