Crop Science & Plant Growth
📋 What it is
Crops need light, water, air, nutrients and the right temperature — and each has ideal conditions.
🗣️ Coach says
Crops are plants grown for food, and each has needs: LIGHT for photosynthesis, WATER, air (CO₂), NUTRIENTS from soil, and a suitable temperature. Farmers match crops to their climate and give them what they lack. Understanding how plants grow lets farmers boost yields and troubleshoot problems.
🧠 Memory hook
Crops need light + water + air + nutrients + right temperature. Match crop to climate; supply what’s missing.

The lettuce won the race because it was a head from the very start.
😲 Whoa!
Corn can grow astonishingly fast in summer — on a hot day a corn plant can grow several centimetres, and a whole field has been said to make faint crackling sounds as it stretches.
