ANSWER: The size of a red blood cell IS approximately half the size of a plant cell.
EXPLANATION:
<em>1. We divide the size of the plant cell by 2 to see if half of its size is the size of a red blood cell. </em>

Therefore, half of a plant cell's size is 0.000006325 m.
<em>2. We now compare the size of half of the plant cell to the size of the red blood cell.</em>
0.000006325 m and 0.000007 m are very close in size; therefore, the size of a red blood cell IS approximately half of a plant cell.
