Answer 1

Size of a plant cell is greater and is greater by 0.00000575 m

Explanation:

Size of a red blood cell

= 0.000007 m

= 7 × 1/1000000 m

Size of a plant cell

= 0.00001275 m

= 1275/100000000

= 1275/(1000000 × 100) m

= 1275/100 × 1/1000000 m

= 12.75 × 1/1000000

∵ 12.75 > 7, 0.00001275 m > 0.000007 m

Now, 0.00001275 m - 0.000007 m

= 0.00000575 m
