Q. The size of a red blood cell is 0.000007m and that of a plant cell is 0.00001275m. Show that a red blood cell is half of plant cell in size . ( NTSE)

Answer 1

Hi friend,
size of res blood cell = 0.000007 = 7*10^-6
size of plant cell = 0.000001275m= 1.275 * 10^-5m
therefore
=>7*10^-6/10. 275*10^-5
=> 7*10^-6 (-5)/1.275
=>7*10^-1/1.275
=> 0.7/1.275
=> 0.7/1.3
=>1/2 (approx)

so a red blood cell is half of plant cell
I hope I helps you

Answer 2

Hello, I am David Alexander, Your question is interesting, and this is your answer .

We have :

Size of a red blood cell = 0.000007m = 7/10^6 m = ( 7 × 10^-6 )m.

Size of a plant cell = 0.00001275m = 1275/10^8m =( 1.275× 10^3 /10^8 )m = 1.275/ 10^(8-3) m = 1.275/10^5m = 1.275× 10^-5 m.

Size of a red blood cell / Size of a plant cell = 7× 10^-6 / 1.275 ×10^-5 = 7×10^-1 / 1.275 = 7/13(nearly) = 1/2( approximately) .

Therefore , size of a red blood cell = 1/2 × size of a plant cell .
