1. Plant Nutrients WALT – Explain what else a plant needs to grow WILF –
Write the effects on the plants of deficiencies in N, P and K
Text book questions , pg 17
Scienctifica handout, qs 1-5, pg 57

2. Non Mineral Nutrients
The Non-Mineral Nutrients are hydrogen (H), oxygen (O), & carbon (C).
But a farmer cannot control the amount of these nutrients the plants in his field gets

3. Mineral Nutrients – 2 types
Macronutrients – A lot of these are needed
Micronutrients – A little of these are needed

4. Macronutrients – Needed in large amounts
 nitrogen (N), 
phosphorus (P),
potassium (K). These major nutrients usually are lacking from the soil first because plants use large amounts for their growth and survival. 
The secondary nutrients are calcium (Ca), magnesium (Mg), and sulfur (S)

5. Micronutrients – needed in small amounts
boron (B), 
copper (Cu), 
iron(Fe), 
chloride (Cl), 
manganese (Mn),
zinc(Zn).
Recycling organic matter such as grass clippings and tree leaves is an excellent way of Replacing nutrients
It is not important that you remember these – just interesting !

6. How are these nutrients transported from root to shoot?
Nutrients are transported from root to shoot through......

7. How are these nutrients transported from root to shoot?
Nutrients are transported from root to shoot through the XYLEM

8. How are the products of Photosynthesis transported from Shoot to the rest of the plant?
The products of Photosynthesis are transported from Shoot to the rest of the plant through......

9. How are the products of Photosynthesis transported from Shoot to the rest of the plant?
The products of Photosynthesis are transported from Shoot to the rest of the plant through the phloem

10. Deficiency Symptoms of the Macroelements
Write the effects on the plants of deficiencies in N, P and K

11. Nitrogen Deficiency General chlorosis (yellowing) of the leaves.
Older leaves showing symptoms first.
N deficiency in potato

12. Phosphorous Deficiency
Reduced plant size
Darkened foliage with a purplish cast.
P deficiency in corn

13. Potassium Deficiency Margins eventually turning brown.
Symptoms develop on lower leaves first.
K deficiency on red currant

14. What are the minerals that are absorbed through the roots used to produce?

15. Add to your drawing the uptake of minerals through the roots
