Question

Assertion : Gaseous exchange takes place in cells
Reason : Concentration of gases are different inside the cells and outside the cells.

Answer 1

Explanation:

Both are correct sentences

Answer 2

Incomplete question:

Assertion: Gaseous exchange takes place in cells

Reason: The concentration of gases is different inside the cells and outside the cells.

Complete question:

(a) Both assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of assertion (A).

(b) Both assertion (A) and Reason (R) are true but reason (R) is not the correct explanation of assertion (A).

(c) Assertion (A) is true but reason (R) is false.

(d) Assertion (A) is false but reason (R) is true.

Answer:

(b) Both assertion (A) and Reason (R) are true but reason (R) is not the correct explanation of assertion (A).

Why is it so?

• Cells exchange gases through the course of diffusion.
• This cycle is described by the development of particles from a locale of higher focus to bring down fixation, along the focus slope.
• In this way, assuming that there is no distinction in the concentration of gases, there will be no gradient consequently causing the diffusion.
• This further aides in not needing energy consequently making it a detached cycle.
