QuestionAnswer
Organism a living thing made up of one or more cells and able to carry on the activities of life
Cell A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things.
Unicellular unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.
Multicellular Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
Metabolism the chemical reactions in the body's cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism.
Stimulus something that excites an organism or part to functional activity.
Response any behavior of a living organism that results from an external or internal stimulus.
Development bringing about social change that allows people to achieve their human potential. ... Furthermore, development is often regarded as something that is done by one group
Asexual reproduction as budding, fission, or spore formation, not involving the union of gametes.
Sexual reproduction reproduction involving the union of gametes.
Spontaneous generation spontaneous generation, the hypothetical process by which living organisms develop from nonliving matter; also, the archaic theory that utilized this process to explain the origin of life.
Autotroph any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists.
Heterotroph an organism requiring organic compounds for its principal source of food.
Classification the establishment of a hierarchical system of categories on the basis of presumed natural relationships among organisms.
Taxonomy the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world.
Binomial nomenclature a system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself.
Genus biological classification ranking between family and species
Species a group of organisms that can reproduce naturally with one another and create fertile offspring
Prokaryote Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages.
Eukaryote Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae.
Nucleus a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.
Evolution In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.
Branching tree diagram A branching tree diagram is a set of groups within groups, with the organisms at the bottom having the fewest shared characteristics and the ones at the top having the most.
Shared derived characteristics A shared derived character is a characteristic or trait that two lineages share, which has evolved leading up to their clade.
Convergent evolution In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities.
