Transport mechanisms — practice question
Marram grass, $\textit{Ammophila arenaria}$, is a key plant of sand dunes. The leaves of marram grass are adapted to minimise water loss through transpiration. Fig. 2.1 shows a photomicrograph of a section through a marram grass leaf.
(a(i))[1]
State one further adaptation shown in Fig. 2.1 that lowers water loss by transpiration.
(a(ii))[2]
Explain in what way this adaptation lowers water loss.
(b)[1]
State the term used for a plant type that has adaptations for reducing water loss through transpiration.
