General Zoology Flashcards

This flashcard set covers the fundamental definitions, characteristics of life, levels of organization, and various specialized branches of zoology and biology as discussed in the General Zoology lecture.

Biology

The science of life.

Characteristics of Life

Key properties shared by all living organisms including order, sensitivity or response to stimuli, reproduction, growth and development, regulation, homeostasis, and energy processing.

Levels of Organization

The hierarchy of living things including atom, molecule, cell organelles, cell, tissue, organ, system of organs, organism, population, bioma, ecosystem, and biosphere.

Phylogenetic Tree

A diagram used to show evolutionary relationships among organisms.

Anatomy

The study of the structure of entire organisms and their parts.

Cytology

The study of the structure and function of cells.

Ecology

The study of the interaction of organisms with their environment.

Embryology

The study of the development of an animal from the fertilized egg to birth or hatching.

Genetics

The study of the mechanisms of transmission of traits from parents to offspring.

Histology

The study of tissues.

Molecular Biology

The study of subcellular details of structure and function.

Parasitology

The study of animals that live in or on other organisms at the expense of the host.

Physiology

The study of the function of organisms and their parts.

Systematics

The study of the classification of, and the evolutionary relationships among, animal groups.

Entomology

The study of insects.

Herpetology

The study of amphibians and reptiles.

Ichthyology

The study of fishes.

Mammalogy

The study of mammals.

Ornithology

The study of birds.

Protozoology

The study of protozoa.

Basic Biology Branches

Subdisciplines including Ecology, Embryology, Evolution, Genetics, Molecular Biology, Morphology, Physiology, and Taxonomy.

Applied Biology Branches

Subdisciplines including Agriculture, Animal Husbandry, Bio-Geography, Economic Biology, Fishery, Forestry, Horticulture, Paleontology, Poultry, Science of Medicine, and Veterinary Science.
