Misconceptions & Reasoning
📋 What it is
Common myths: “plants get food from soil”, “plants don’t breathe”, “bigger plant = older plant”.
🗣️ Coach says
Botany has sticky myths. Plants MAKE their food from sunlight — soil gives water and minerals, not food. Plants DO breathe (respire) all the time, not just photosynthesise. And size doesn’t equal age — a tiny bonsai can be a century old. A good scientist checks intuition against evidence.
🧠 Memory hook
Plants MAKE food (not from soil). Plants DO respire. Size ≠ age.
😂 Giggle
The weed went to court, but the case was dismissed — it planted itself there first.
😲 Whoa!
A bonsai tree can be over 100 years old yet stay small — carefully pruned, so its tiny size tells you nothing about its age.
✅ Quick check: True or false: “Plants get their food from the soil.”
Say your answer out loud first — then reveal.
False — plants MAKE food from sunlight (photosynthesis); soil provides water and minerals, not food.
Plants produce food via photosynthesis; soil supplies water and nutrients only.
