How would this change in the timing of cell division affect the structure and life cycle of plants in this lineage?

Greatly affect the structure and life cycle of plants.

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.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
