(a) (i) State the role of ATP in cellular respiration.
(ii) What ensures sufficient exchange of gases in plants ?
(iii) State the conditions on which the direction of diffusion of gases in plant depend upon.
Solution
(a) (i) Energy currency for cellular processes / ATP breaks down to give a fixed amount of energy which can drive the endothermic reactions taking place in the cell.
(ii) Stomata and surface of leaves, stems and roots.
(iii) Environmental conditions
Requirements of the plant.
