Diversity of Living World - General Zoology

Flashcards covering key vocabulary and concepts from the lecture on biodiversity and general zoology.

Biodiversity

The combined diversity at all levels of biological organization, including genetic, species, and ecological diversity.

Species

The basic unit of classification, representing a group of individuals that can interbreed and produce fertile offspring.

Metabolism

The sum total of all chemical reactions occurring in the bodies of organisms.

Protoplasm

The living substance within a cell, consisting of cytoplasm and nucleus, containing genetic material DNA.

Homeostasis

The maintenance of relatively constant internal conditions within a living organism.

Nomenclature

The system or process of naming organisms according to the guidelines of the International Code of Zoological Nomenclature.

Taxonomy

The science of classification of living organisms.

Evolution

The process by which life changes over time, advancing from simpler forms to more complex forms.

Parazoa

Multicellular animals without well-defined tissues, such as sponges.

Eumetazoa

Multicellular animals with well-defined tissues and higher levels of organization.

Phylogenetic Classification

Classification based on evolutionary relationships and common ancestry among organisms.

Genetic Diversity

The variety of genes within a species.

Species Diversity

The variety of species found in a particular habitat or ecosystem.

Ecological Diversity

The variety of ecosystems within a given area.

Binomial Nomenclature

A system of naming organisms using two names, typically the genus and species.

Cellular Organization

The arrangement of cells into functional structures, fundamental to all living organisms.

Sensitivity in Organisms

The ability of organisms to respond to external and internal stimuli.
