Practice question · Match the pairs
Match each kingdom to the strategy it used on land.
- Plants
- Fungi
- Arthropods
- Amniote vertebrates
- An exoskeleton solving support and water loss together
- A shelled egg that carries its own water supply
- Vascular tissue, lignin and seeds
- A mycelium feeding by external digestion
Hints
- Each group solved the same problems with different equipment.
- One group carries its own private pond inside an egg.
Show the answer
- Plants → Vascular tissue, lignin and seeds
- Fungi → A mycelium feeding by external digestion
- Arthropods → An exoskeleton solving support and water loss together
- Amniote vertebrates → A shelled egg that carries its own water supply
Why
The same set of problems produced four quite different solutions. The amniotic egg is the most elegant: it encloses an aquatic environment, letting vertebrates reproduce entirely away from water.
