1. Question 1Skills & concepts

   Icelandic moss is notable among mosses for being used by some cultures as

   • afood, such as in tea and soup
   • ba building material only
   • ca source of antibiotics only
   • dfuel for vehicles
2. Question 2Strategic thinking

   A student examines an unknown plant and finds it lacks true roots, stems and leaves, but has rhizoids and a seta-capsule structure. Identify the plant group and explain your reasoning.

   • aMoss (Bryophyte) — the lack of true roots/stems/leaves and presence of rhizoids and a seta-capsule (sporophyte) are defining bryophyte features
   • bFern (Pteridophyte) — ferns also lack true roots, stems and leaves
   • cFlowering plant — these features are typical of angiosperms
   • dRhizopus — fungi have setae and capsules
3. Question 3Extended thinking

   Ferns are vascular (having xylem and phloem) while mosses are non-vascular. Using this distinction, explain why ferns can grow much taller than mosses and colonise a wider range of habitats.

   • aVascular tissue in ferns allows efficient long-distance transport of water and nutrients, supporting larger structures and a wider range of habitats, while mosses without vascular tissue are limited to small sizes and damp environments
   • bMosses are vascular and ferns are non-vascular
   • cVascular tissue has no relationship to plant height or habitat range
   • dFerns and mosses have identical transport systems
