Question
The volume of the sea Urchin egg is 5.2 x 10^5 µm3. You fertilize the cells and take measurements of cellular dimensions at the four blastomere stage. Assume a perfect sphere.
Question: What would you predict is the surface area of EACH the sea urchin blastomeres?
A) 1 x 10^2 µm^2
B) 5.66 x 10^5 µm^2
C) 6.66 µm^2
D) 3.9 x 10^5 µm^2
E) 1.24 x10^4 µm^2
F) None of these
Expert Solution
Step 1
a given volume of the sea urchin egg =5.2 x 10^5 µm3
using the formula volume of the sphere =
V=4/3πr3
V =5.2 x 10^5 µm3
π =3.14
on calculating the resultant radius of the sphere i.e... the radius of the 1 blastomeres
as the egg consists of 4 blastomeres paires
r= 0.310x10^5 µm
