basic concepts

1. GOOD MORNING!

2. MORPHOLOGY
THE STUDY OF EXTERNAL FORM AND
STRUCTURE.
• HABIT
• PLANT PARTS
• ROOT, STEM, LEAVES, FLOWERS,
INFLORASCENCE, FRUIT,SEED

3. HABIT
• HERBS
• SHRUBS
• TREES

4. HERBS
• ANNUALS
• SOFT STEM
• AROUND ONE FEET IN HEIGHT
• MOSTLY MONOCARPIC

5. SHRUBS
• MOSTLY PERENNIALS
• WOODY STEM UP TO THREE METERS IN
HEIGHT
• MOSTLY POLYCARPIC

6. TREES
• PERENNIALS
• MANY METERS IN HEIGHT
• MOSTLY POLYCARPIC RARELY MONOCRPIC

7. ROOTS
• ORIGIN
• TAPROOT
• FIBEROUS ROOT
• ADVENTITIOUS ROOT

8. ORIGIN
• DEVELOPS FROM THE RADICLE OF THE
EMBRYO.

9. TAPROOT
• PRIMARY ROOT CONTINUES TO GROW
INDEFENITELY, GIVING OFF BRANCHES.

10. FIBEROUS ROOT
• PRIMARY ROOT STOPS GROWTH AFTER A
PERIOD OF GROWTH.
• SEVERAL ROOTS ARISE IN CLUSTER FROM THE
BASE OF THE STEM

11. ADVENTITIOUS ROOT
• DEVELOPS FROM ANY REGION OTHER THAN
RADICLE.

12. FUNCTION
• ANCHORAGE, ABSORBTION
• SPECIAL FUNCTIONS
• STORAGE, SUPPORT, PROPAGATION, GASEOUS
EXCHANGE, PHOTOSYNTHESIS.

13. STEM
ORIGIN
• POSITION
• NODES, INTERNODES
• PROSTRATE, ERECT
• BRANCHED, UNBRANCHED
• POSITION
• FUNCTION

14. FUNCTIONS
• BEARING OF BRANCHES, LEAVES, FLOWERS
AND FRUITS
• EXPOSURE OF LEAVES TO THE SUNLIGHT
• PHOTOSYNTHESIS
• STORAGE
• PROPAGATION
• ABSORBTION

15. LEAVES
• POSITION
• PARTS
• FUNCTION
• KINDS

16. Simple leaf
