Answer:
Greatly affect the structure and life cycle of plants.
Step-by-step explanation:
The timing of cell division greatly affect the structure and life cycle of plants because if the cell division occurs very fast, the plants grow very quickly and completes its life cycle, while on the other hand, if the cell division takes too much time to completion, very slow growth in the size and structure of plant occurs. So normal timing of cell division is very important for structure and life cycle of plants.
