Plant and Animal Classification

complete metamorphosis

• A gradual change in form from juvenile to adult stages

• A change in form from one stage to the next in the life history of an organism (ex. egg, larva (caterpillar), pupa (chrysalis), adult butterfly)

• A transformation that occurs only in mammals

• A process of reproduction in plants

Flowering Plants

• plants that reproduce with flowers

• plants that reproduce with seeds

• plants that reproduce with spores

• plants that do not reproduce sexually

Nonflowering Plants

• plants that reproduce by seeds

• plants that reproduce by spores, not flowers

• plants that have colorful flowers

• plants that require sunlight to grow

Life Cycle

• the stages an organism’s growth and development

• a period of inactivity in an organism

• the process of reproduction in organisms

• the environmental conditions affecting an organism's life

Reptile

• an animal that has a backbone and dry, leathery skin or scales; breathes air with lungs; lays eggs with leathery shells or sometimes gives birth to live young

• a warm-blooded animal that has feathers and lays eggs

• a cold-blooded animal that lives in water and has gills

• a mammal that gives birth to live young and has fur or hair

incomplete metamorphosis

• type of insect development characterized by the similar appearance of pre-adults and adults.

• a process where insects undergo a complete transformation from larva to adult.

• a developmental stage where insects have distinct larval and adult forms.

• a type of metamorphosis that occurs only in amphibians.

Pupa

• a stage in the life cycle of an insect that occurs between larva and adult

• a type of adult insect

• a stage where insects lay eggs

• a stage of metamorphosis before larva

Nymph

• the larval stage of a butterfly

• the offspring of an insect that goes through incomplete metamorphosis; it generally appears much like the adult without going through a pupal stage.

• a type of aquatic plant

• a fully developed adult insect

Bird

• an animal with a backbone, feathers, wings, and lightweight bones, breathes air, and lays eggs with a hard shell

• a mammal that gives live birth and has fur

• a reptile that lays soft-shelled eggs and has scales

• an amphibian that can live both in water and on land

Amphibian

• an animal that has a backbone and lives in water when it is young and land when it is an adult

• a type of reptile that can fly

• a mammal that primarily lives in trees

• a fish that can breathe air
