Dichotomous Key Practice Worksheet for Identifying Leaves

I'll solve this dichotomous key practice problem by identifying each of the 5 leaves (A-E) using the provided key.

Let me start by examining each leaf and applying the dichotomous key step by step.

First, I'll look at Leaf A:
- It appears to be oval shaped (not star shaped)
- According to Step 1: 1A (Leaf is oval shaped) → Go to Step 2
- In Step 2: It looks shorter and wider (not longer and narrower)
- According to Step 2: 2A (Leaf is shorter wide) → Go to Step 4
- In Step 4: I need to count the veins on each side. Looking closely, it appears to have 4 veins on each side.
- According to Step 4: 4A (Leaf has 4 veins on each side) → Birch

Now, let me examine Leaf B:
- It appears to be oval shaped (not star shaped)
- According to Step 1: 1A (Leaf is oval shaped) → Go to Step 2
- In Step 2: It looks longer and narrower (not shorter and wider)
- According to Step 2: 2B (Leaf is longer and narrow) → Hickory

Next, Leaf C:
- It appears to be star shaped (not oval shaped)
- According to Step 1: 1B (Leaf is star shaped) → Go to Step 3
- In Step 3: It has jagged edges (not smooth edges)
- According to Step 3: 3B (Leaf has jagged edges) → Sugar Maple

Now, Leaf D:
- It appears to be oval shaped (not star shaped)
- According to Step 1: 1A (Leaf is oval shaped) → Go to Step 2
- In Step 2: It looks shorter and wider (not longer and narrower)
- According to Step 2: 2A (Leaf is shorter wide) → Go to Step 4
- In Step 4: I need to count the veins on each side. Looking closely, it appears to have 5 veins on each side.
- According to Step 4: 4B (Leaf has 5 veins on each side) → Beech

Finally, Leaf E:
- It appears to be star shaped (not oval shaped)
- According to Step 1: 1B (Leaf is star shaped) → Go to Step 3
- In Step 3: It has jagged edges (not smooth edges)
- According to Step 3: 3B (Leaf has jagged edges) → Sugar Maple

Wait, I need to double-check Leaf E. It looks very similar to Leaf C, but let me verify if they're both Sugar Maple or if one might be different. Looking more carefully, both C and E appear to be star-shaped with jagged edges, so they would both be identified as Sugar Maple according to the key.

Actually, let me reconsider. The key only provides one option for star-shaped leaves with jagged edges (Sugar Maple), so both C and E would be classified as Sugar Maple based on this dichotomous key.

Let me summarize my findings:
- A: Birch
- B: Hickory
- C: Sugar Maple
- D: Beech
- E: Sugar Maple

This completes the identification of all 5 leaves using the dichotomous key.
