Vertebrates and Invertebrates

Flashcards reviewing vertebrates, invertebrates, and plant classification.

Vertebrates

Animals that have a vertebral column or backbone.

Chordata

An animal phylum that includes all vertebrates.

Fish

Vertebrates that live in water and have fins and gills.

Amphibians

Vertebrates that live on land but return to water to breed and have smooth, moist skin.

Reptiles

Vertebrates that have dry, scaly skin and lay eggs with waterproof shells.

Birds

Vertebrates with feathers and wings, capable of controlling their body temperature.

Mammals

Vertebrates with hair or fur and mammary glands, capable of controlling their body temperature.

Invertebrates

Lacking a vertebral column or backbone.

Arthropods

The largest group in the animal kingdom; segmented animals with jointed legs and an exoskeleton.

Crustaceans

Arthropods with two body regions (abdomen and cephalothorax), a chalky exoskeleton, and gills for breathing.

Myriapods

Arthropods having many body segments with one or two pairs of legs on each segment.

Centipedes

Fast-moving carnivores with one pair of legs per segment that can paralyze their prey.

Millipedes

Slow-moving herbivores with two pairs of legs per segment that feed on leaf litter.

Insects

Arthropods with three body regions (head, thorax, and abdomen), spiracles for breathing, and waterproof cuticles.

Arachnids

Arthropods with two body regions (cephalothorax and abdomen), spinnerets for producing webs, and poison fangs.

Monocotyledons

Flowering plants with one cotyledon in the seed, long and narrow leaves, and flower parts in multiples of three.

Dicotyledons

Flowering plants with two cotyledons in the seed, broad leaves with branching veins, and flower parts in multiples of four or five.
