Dichotomous Key

1a. Needle leaves: go to step 2

1b. Non-needles leaves: go to step 3

2a. Needles are grouped in clusters: pine tree

2b. Needles are individually arranged: spruce tree

3a. Simple (individual) leaves: go to step 4

3b. Compound leaves (leaflets): go to step 5

4a. Leaf edge is smooth and lobed: oak tree

4b. Left edge is rough and tooth-like: elm tree

5a. Leaflets are attached at one point: chestnut tree

5b. Leaflets are attached at many points: walnut tree



Examine the leaf.

Non-needle green leaf with compound leaves attached at the center.

What kind of tree is the leaf from?

chestnut

walnut

elm

oak

It is from a chestnut tree.

What is that??

A chestnut tree is a tree that produces chestnuts, which are edible nuts. They are typically grown in temperate regions and are known for their distinctive, prickly fruit casings. Chestnut trees are also known for their timber, which is strong and durable, making it suitable for use in furniture and construction.

Oh okay.!!

Is there anything else I can help you with?

To determine the kind of tree the leaf is from using the dichotomous key, follow these steps:

1. Start at Step 1a: Needle leaves. However, since the leaf in question is a non-needle green leaf, we skip to Step 1b: Non-needle leaves.

2. Move to Step 3b: Compound leaves (leaflets) since the leaf in question has compound leaves attached at the center.

3. Now, we move to Step 5a: Leaflets are attached at one point and Step 5b: Leaflets are attached at many points.

4. Since the leaflets are attached at many points, we can conclude that the leaf is from a walnut tree.

Therefore, the correct answer is "walnut."
