Question

use this portion of a dichotomous key for tree identification to answer the question.
1a. needlelike leaf ➔ step 10
1b. broad leaf ➔ step 2
2a. compound leaf ➔ step 3
2b. simple leaf ➔ step 7
3a. leaves attached at single point ➔ buckeye
3b. leaves attached at many points ➔ step 4
4a. leaf bases attached opposite each other on branch ➔ ash
4b. leaf bases attached staggered on branch ➔ step 5

what are the characteristics of a buckeye leaf?
○ needlelike simple leaves attached opposite each other on the branch
○ broad simple leaves attached at single points on the branch
○ broad compound leaves attached at single points on the branch
○ needlelike compound leaves attached staggered on the branch

Explanation:

To determine buckeye leaf characteristics, follow the dichotomous key:

1. Buckeye is reached via 1b (broad leaf) → 2a (compound leaf) → 3a (leaves attached at single point). So buckeye leaves are broad, compound, and attached at a single point on the branch.

Answer:

C. broad compound leaves attached at single points on the branch (assuming option labels: if options are labeled as A - D, identify the correct one with its text. Here, the third option matches the deduction.)
