Question

a dichotomousys key is used to identify a plant.
1a. leaves are spiny.......... pinus taeda
1b. leaves are broad..........go to 2

2a. single leaf..........go to 3
2b. Mant leaves......... go to 4

3a. Leaf edge is smooth..........cornus florida
3b. Lead edge is rough.......... ulmus ameriana

4a. leaflet edges are smooth.......... albizia julibrissin
4b. leaflet edges are rough......... juglans nigra



a plant has mant broad leaves with rough edges.
what type of plant is this?

Answer 1

you sure

Answer 2

Based on the dichotomous key you provided, a plant with "mant leaves" and "rough edges" would lead us to:

1. You go to 4 because it has "mant leaves."
2. Since the leaflet edges are rough, it corresponds to:

**Juglans nigra** (Black Walnut).

Answer 3

Yes, based on the dichotomous key you provided, a plant with "mant leaves" (presumably you meant "many leaves") and "rough edges" would indeed lead to **Juglans nigra**.

Here’s the reasoning again:
1. Since the plant has **many broad leaves**, you go to step 4.
2. Within step 4, if the **leaflet edges are rough**, it identifies as **Juglans nigra**.

If there are any discrepancies or if you meant something else by "mant leaves," please clarify, and I’d be happy to assist further!
