Food in form of sugar – used for energy

1. Nutritional Needs of plants • Food in form of sugar – used for energy • 2. Glucose, light, water, air, suitable temperature, minerals • 3. Food = energy minerals = healthy development • 4. Mixtures used for proper growth and development • 5. Increase surface area, increase absorption of water and minerals • 6. Evaporates out of leaf • 7. Deplete soil’s natural mineral supply • Recycle leaves and grass or add fertilizer • 8. Different concentrations of basic nutrients

2. 9. Nitrogen, phosphorus, potassium • 10. 29 = % of N - nitrogen, • 3 = % of P- phosphorus, • 4 = % of K = potassium • 11. Healthy leaves • Not enough= light green leaves, thin stem too much = large leaves • but small flowers • 13. Healthy roots and flowers • tulips, newly planted trees • Leaves turn dark, purple/blue • 15. Survive dramatic temperature changes, protect • from disease • 16. Brown droopy leaves
