Plant Adaptations & Evolution
📋 What it is
Plants evolve adaptations — thorns, deep roots, waxy leaves — to survive their environment.
🗣️ Coach says
Plants can’t run, so they adapt in place. A cactus stores water and swaps leaves for spines to survive deserts; a rainforest vine climbs toward scarce light; some seeds need FIRE to sprout. Over generations, natural selection shapes these clever solutions to each habitat.
🧠 Memory hook
Plants adapt in place: cactus spines, deep roots, waxy leaves — selection shapes them.
😂 Giggle
The flower didn't ride its bike to school because it lost its petals.
😲 Whoa!
Some pine cones stay sealed shut until a forest fire’s heat pops them open — the plant evolved to reproduce right after a fire clears its competition.
✅ Quick check: Why does a cactus have spines instead of broad leaves?
Say your answer out loud first — then reveal.
Spines lose far less water than leaves (and deter animals) — an adaptation for surviving the dry desert.
Reduced leaf area conserves water, an adaptation to arid habitats.
