K.C.S.E Biology Q & A - MODEL 2018PP1QN04
A group of form two students placed a fresh leaf in warm water. They observed that air bubbles formed on the surface of the leaf.
(a) What biological process were they investigating?
(b) Name the structures from which the air bubbles were coming from.
(c) Explain the distribution of the structures named in (b) above on the leaf surfaces of a land plant.
a) Photosynthesis;/gaseous exchange in plants;
c) Are more on the lower surface of terrestrial plants/fewer on the upper surface; to reduce transpiration;
