Cell growth and the rate of cell division in multicellular organisms vary between different types of cells. Organism growth and repair occur as cells progress through the different phases of the cell cycle. Why is the cell cycle important to the growth of organisms?
a)
The cell cycle allows for all genetic information to be copied before cell division occurs so that each daughter cell has everything it needs to survive.
b)
The cell cycle allows for new genetic information to be processed so that the daughter cells can be altered to meet new needs of the organism.
c)
The cell cycle allows cells to grow to larger sizes to accommodate the increase in size of the organism as the organism grows.
d)
The cell cycle allows for the organism to make its own food when food sources are scarce.
