1

What are plant nutrients for?

to grow well and produce high yields

2

Name the main macronutrients...
a)
b)
c)

a) carbon
b) hydrogen
c) oxygen

3

How are the remaining nutrients taken in by the plants?

in the form of mineral salts (dissolved in the soil through fertilisation)

4

List all Macronutrients

Carl HyMaO PoNi SuP

5

Functions of C,O,H. (2)

-important for carbon cycle & oxygen cycle
-synthesis of sugar

6

Effects X C,O,H (2)

-photosynthesis cannot take place (less oxygen)
-stunted growth [death] {no glucose how to live...}

7

Functions of Ca. (1)

-main component for middle lamella, cell wall & spindle fiber during cell division

8

Effects X Ca (3)

-stunted growth
-leaves distorted & lobed
-leaf veins become yellowish

9

Functions of Ma (3)

-main chlorophyll molecule
-activates enzymes
-carbohydrate metabolism

10

Effects X Ma (3)

-matured leaves yellowish
-red spot on leaf
-lobed leaves

11

Fuctions of Po (K) (3)

-protein synthesis & carbohydrate metabolism
-cofactor
-maintain plant turgidity

12

Effect X Po (K) (2)

-leaf edges yellowish
-premature death

13

Function of Ni (Nitrogen) (2)

-give green colour (formation of chlorophyll)
-main for proteins, nucleic acid and enzymes (in photo & respi)

14

Effect X Ni (Nitrogen) (4)

-chlorosis
-underlying leaves fall
-protein synthesis disrupt
-stunted growth

15

Function of Su (2)

-component for some amino acids
-component for vitamin B & some coenzymes

16

Effects X Su (1)

-leaves/plant turns yellow

17

Function of Pho (P) (2)

-synthesise nucleic acid, ATP, phospholipids
-coenzyme in photo & respi

18

EffectsX Pho (P) (3)

-unhealthy root growth
-form dark green & dull leaves
-red / purple spots appearing on older leaves

19

List all micronutrients...

ChloZi ICoMn NiBoMo

20

Function of Chlo (2)

-osmotic pressure
-photosynthesis

21

Effects X Chlo (4)

-plant wilts
-slower root growth
-chlorosis
-less fruit

22

Function of Zi (3)

-leaf formation
-auxin synthesis
-cofactor for carbohydrate metabolism

23

Effects X Zi (2)

-chlorosis spots on leaves
-stunted growth

24

Function of I (Fe) (2)

-cofactor for chlorophyll synthesis
-growth of young plants

25

Effects X I (Fe) (1)

-Young leaves yellowish

26

Function of Co (2)

-nitrogen metabolism & photosynthesis
-growth, repro & flower

27

Effects X Co (3)

-young shoot apex dead
-brown spot on terminal leaves
-stunted

28

Functions of Mn (2)

-activates photosynthetic enzymes
-cell respi & nitrogen metabolism

29

Effects X Mn (2)

-network dark green leaf veins
-light brown / grey spots between leaf veins

30

Functions of Ni (1)

-involved in urea breakdown --> ammonia [used by plant]
