Question

Assertion (A) : Smaller cells usually metabolically active cells.
Reason (R) Smaller cell nucleocytoplasmic
ratio and have higher surface volume ratio.
(a) Both A and R are true and R is correct
explanation of A
(b) Both A and Rare true, but is not the
correct explanation of A
(c) A is true, but R is false
(d) A is false, but R is true​

A

Explanation:

both A nd R is correct

not sure but I think it's true

Answer 2

Answer:

the correct answer is both the A and  is true and  R is the correct explanation of A

Explanation:

• Small cells have more surface area than the large cell.With the smaller cells , there is more surface area which is available for oxygen and nutrients to diffuse in and carbondioxide to diffuse out of the cell
• More smaller cells are take oxygen and nutrients and releases  carbondioxide much more quicker than large one
• When there s more surface volume and area which takes less efficiency
