| a tool used to identify organisms based on different pairs of characteristics | dichotomous key or dichotomous questions |
| plants that have a water transport system - they have roots, stems, and leaves | vascular |

| a vascular plant that produces seeds in cones or berries; pine trees and grass are examples | gymnosperm |
| an animal without a backbone | invertebrate |
| the highest level of classification; this is the least specific category | domain |
| plants that lack a water-transport system | nonvascular |
| an animal with a backbone | vertebrate or chordata |
| a cold-blooded vertebrate that lays eggs, has scales, and claws | reptile |
| a cold-blooded vertebrate that lays eggs, has scales, and breathe with gills | fish |
