Problem Overview:
The task is to match each part of a leaf with its function and then label the diagram accordingly. The leaf parts are listed on the left, and their functions are provided on the right. We need to identify the correct function for each part and use that information to label the diagram.
Leaf Parts and Their Functions:
1.
Cuticle: This is a waxy layer on the surface of the leaf.
2.
Guard Cell: These cells control the opening and closing of stomata.
3.
Lower Epidermis: This is the outer layer on the underside of the leaf.
4.
Upper Epidermis: This is the outer layer on the top side of the leaf.
5.
Palisade Cell: These cells are involved in photosynthesis.
6.
Spongy Layer: This is the inner tissue of the leaf, which contains air spaces.
7.
Stoma (plural: stomata): These are small pores on the leaf surface.
8.
Vein: These are vascular structures that transport water and nutrients.
Matching the Functions:
Now, let's match each leaf part with its function:
1.
Cuticle:
- Function: Prevents water loss.
- Match:
A. prevents water loss
2.
Guard Cell:
- Function: Controls transpiration by opening and closing stomata.
- Match:
H. controls transpiration by opening and closing stomata
3.
Lower Epidermis:
- Function: Has pores (stomata).
- Match:
F. has pores
4.
Upper Epidermis:
- Function: Produces the cuticle and protects the leaf.
- Match:
B. produces the cuticle and protects the leaf
5.
Palisade Cell:
- Function: Makes most of the food (photosynthesis).
- Match:
C. makes most of the food
6.
Spongy Layer:
- Function: Leaves room for carbon dioxide to move in and oxygen to move out.
- Match:
D. leaves room for carbon dioxide to move in and oxygen to move out
7.
Stoma:
- Function: Lets carbon dioxide in and oxygen out.
- Match:
G. lets carbon dioxide in and oxygen out
8.
Vein:
- Function: Brings water up from the roots into the leaf and carries food to all other parts of the plant.
- Match:
E. brings water up from the roots into the leaf and carries food to all other parts of the plant
Labeling the Diagram:
Using the matches above, we can now label the diagram:
1.
Cuticle: Topmost layer on both sides of the leaf.
2.
Guard Cell: Surrounds the stomata.
3.
Lower Epidermis: Outer layer on the underside of the leaf.
4.
Upper Epidermis: Outer layer on the top side of the leaf.
5.
Palisade Cell: Layer just below the upper epidermis.
6.
Spongy Layer: Inner tissue with air spaces.
7.
Stoma: Small pore on the leaf surface.
8.
Vein: Vascular structure labeled in the diagram.
Final Answer:
- Cuticle:
A
- Guard cell:
H
- Lower epidermis:
F
- Upper epidermis:
B
- Palisade cell:
C
- Spongy layer:
D
- Stoma:
G
- Vein:
E
Labeled Diagram:
- Topmost layer (cuticle): "Cuticle"
- Outer layer on the underside (lower epidermis): "Lower Epidermis"
- Outer layer on the top side (upper epidermis): "Upper Epidermis"
- Layer just below the upper epidermis (palisade cells): "Palisade Cells"
- Inner tissue with air spaces (spongy layer): "Spongy Layer"
- Small pore (stoma): "Stoma"
- Vascular structure (vein): "Vein"
Final Answer:
\boxed{
\begin{aligned}
&\text{Cuticle: A} \\
&\text{Guard cell: H} \\
&\text{Lower epidermis: F} \\
&\text{Upper epidermis: B} \\
&\text{Palisade cell: C} \\
&\text{Spongy layer: D} \\
&\text{Stoma: G} \\
&\text{Vein: E}
\end{aligned}
