State True or False:
New cells can arise by the division of similar pre-existing cells.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement claims that new cells can arise by the division of similar pre-existing cells. This means that existing cells can divide to form new cells.

2. **Cell Theory Reference**: According to the cell theory proposed by scientists Schleiden and Schwann, one of the key postulates states that all new cells come from the division of existing cells. This supports the idea that new cells arise from pre-existing cells.

3. **Definition of Parent Cells**: The cells that divide to form new cells are referred to as parent cells. When a parent cell divides, it undergoes a process called karyokinesis (division of the nucleus) followed by cytokinesis (division of the cytoplasm).
