Q.

Why the number of stomata are more on the lower side of the leaf than on the upper side in most of the plants?

Q. Given below is a list of different steps (i-vi) involved in respiration.
(i) Utilisation of $O_2$ by the cells for catabolic reactions
(ii) Transport of gases by the blood
(iii) Pulmonary ventilation by which atmospheric air is drawn in and $C{O}_2$ is released out
(iv) Release of resultant $C{O}_2$
(v) Diffusion of $O_2$ and $C{O}_2$ between blood and tissues
(vi) Diffusion of gases ($O_2$ and $C{O}_2$) across alveolar tissues.
Select an option which has correct sequence of all the steps.

1. (iii), (vi), (ii), (v), (i), (iv)
2. (iii), (vi), (i), (v), (ii), (iv)
3. (iv), (ii), (v), (iii), (i), (vi)
4. (iv), (vi), (ii), (v), (i), (iii)
