Question

The size of the red blood cells is 0.000007 m and size of the plant cell is 0.00001275 m. What is the
approximate ratio of their sizes?​

Answer 1

Answer:

Step-by-step explanation:

Size of red blood cell =0.000007m = 7 × 10-6m

Size of red blood cell =0.000001275m= 1.275 × 10-5m

Therefore

7×10-6/1.275×10-5

0.000007/0.00001275

7/0.1275

1/2(approx) = 54.901

So a red blood cell is half of plant cell in size
