MUHAMMAD AFAQ KHALID

2. Basic Structure of a Tree
 Stem
 Root
 Leaf

3. Root
Functions:
 Absorb water and nutrients
 Store food
 Anchor plant, Support the above ground part of plants

4. Root
Root Systems:
 Fibrous Root
No dominant primary root.
 Tap Root:
Dominant primary root.

5. Root
 Primary Root:
First root after the germination. May become main tap root.
 Secondary Root:
Root branch out from primary root
 Root apical Meristem:
Area at the tip of root have ability to develop new cell.

6. Stem
Function:
 Support the leaves, and positions them so they can receive as much
sunlight as possible.
 Responsible for the size and shape of the plant.
 Move water, minerals, and manufactured food throughout the whole.
 Green stems produce food through photosynthesis.

7. Stem
Internal Structures
 Phloem:
Phloem is the living tissue that transports the soluble organic
compounds made during photosynthesis.
 Cambium:
 Xylem:
Non-living tissue that transport water.
 Pith:
Inner part of stem.
 Epidermis:
 Cortex:

8. Leaf:
Leaf Functions
 Manufacture food through photosynthesis
 Gas (Air) Exchange – Respiration
 Protect vegetative and floral buds
 Water Transport – Transpiration
 Store Food During Germination
