3. adaption of a plant - Adaptations are special traits or features that allow a plant or animal to live in a specific habitat; this cactus has adaptations to help conserve water.
4. amniotic egg - An amniotic egg is an egg produced by reptiles, birds, and egg-laying mammals; the embryo of the egg develops inside an amnion protected by a calcium-based or leathery shell. This chicken egg is an example of an amniotic egg.
6. angiosperm - Angiosperms are seed-producing plants that have flowers/fruits; these orchids are an example of angiosperms.
8. arachnid - Arachnids are invertebrate animals that have eight legs; this spider is an example of an arachnid.
10. arthropod - An arthropod is an invertebrate animal that has an exoskeleton, a segmented body, and joint appendages; this ladybug is an example of an arthropod.
12. bilateral symmetry - Bilateral symmetry is the arrangement of an organism or body part so that it is divided into equal halves; these succulents show bilateral symmetry
14. chordate - Chordates are animals that has a notochord (flexible support rod), a hollow nerve cord, an endostyle (mucus secreting structure), and a tail that extend behind the anus. These frogs are an example of chordates.
20. fungi - Fungi are organisms that are composed of small chitin shells and include mushrooms, yeasts, and molds. They are essential in decomposing organic matter in the soil and have many uses; these oyster mushrooms are an example of fungi
21. gastropod - A gastropod is any organism belonging to the Gastropoda class such as the snail or slug. Some of the characteristics of a gastropod include a coiled shell or no shell at all, a foot for locomotion, and eyes/antenna on their head. these gold mystery snails are an example of aquatic gastropods.
22. genetic variation - Genetic variation is the genetic difference within and among a population; the differing colors on the leaves of this poinsettia are a result of genetic variation.
24. gymnosperm cone - gymnosperms are seed-producing plants that have seeds that develop and are often modified to form cones; this pine cone is an example of a gymnosperm cone.
25. gymnosperm leaf - The seeds of a gymnosperm are often unenclosed, which gives the gymnosperm it name ("naked seeds"). This redwood is one example of a gymnosperm because it has needles rather than leaves
28. modified leaf of a plant - A modified leaf of a plant is a leaf that has been modified to perform a function other than photosynthesis and transpiration. The leaves of this Christmas cactus have been modified to conserve water.
29. modified root of a plant - In some plants, roots are modified to perform multiple functions such as storage. This potato is an example of a modified plant root because it has been used as storage.
30. modified stem of a plant - A modified stem is a stem that has been specialized or transformed to serve a particular function. This rose bush has grown thorns on its stems to protect itself from herbivores.
33. organisms in different plant divisions - A phylum is a level of classification in biology between kingdom and class; the term division is more traditionally used in botany (plant biology).
Fern - Pteridophyta
Flower - Magnoliophyta
Evergreen pine - Pinophyta
38. seedless vascular plant - Seedless vascular plants are plants that reproduce by means of spores; this selaginella fern is an example of a seedless vascular plant.
39. tetrapod - A tetrapod is a vertebrate land animal that usually has four legs and feet; this chiweenie (Chihuahua Dachshund cross breed) is an example of a tetrapod because it has a spine and four legs and feet.
