OBSERVING THE ANATOMICAL STRUCTURE OF THE LEAF


Discussion

Table  : The function of the leaf tissue

1.      The function of dicotyl leaf tissue

No.
The dicotyl leaf parts
Theirs function
1.
Epidermis tissue
Protects and covers the underlying tissue
2.
Palisade
The location of photosynthesis process
3.
Spongy tissue
The location of photosynthesis
4.
Vascular bundle
Consist of:
-          Xylem
-          Phloem


Transport water and minerals from roots to leaves
As the carries of nutrients from the leaves throughout the plant body
5.
Stoma
The place of gas exchange
6.
Cuticle layer
a waterproof epidermal layer that blocks water loss

2.      The function of monocotyl leaf tissue

No.
The monocotyl leaf parts
Theirs function
1.
Epidermis tissue
Protects and covers the underlying tissue
2.
Spongy tissue
The location of photosynthesis
3.
Vascular bundle
Consist of:
-          Xylem
-          Phloem


Transport water and minerals from roots to leaves
As the carries of nutrients from the leaves throughout the plant body
4.
Stoma
The place of gas exchange
5.
Cuticle layer
a waterproof epidermal layer that blocks water loss
6.
Parenchyma tissue
in storage, photosynthesis, and as the bulk of ground and vascular tissues

Conclusion
