○Response to the enviornement
○Evolutionary adaptation
○Regulation
○Reproduction
●5 unifying themes
○Organization
○Information
○Energy and matter
○Interactions
○Evolution
●Biological organization
○Biosphere- all life on Earth and all the places where life exists
○Ecosystems- all the living things in a particular area along with
all the nonliving components of the environment which life
interacts with
○Communities- the collection of organisms inhabiting a
particular ecosystem
○Populations-all the individuals of a species living within the
bounds of a specified area
○Organisms-individual living things
○Organs- a body part that is made up of multiple tissues and
have a specific function in the body. Example- leaves, stems,
roots for the plant
○Tissues: group of cells that work together performing a
specialized function.
Document Summary
1 lecture notes: fundamental themes and concepts/evolution/themes of biology. Characteristics of living things: reproduction, movement, using energy, organization, adaptation, reactions to environment. Biosphere- all life on earth and all the places where life exists. Ecosystems- all the living things in a particular area along with all the nonliving components of the environment which life interacts with. Communities- the collection of organisms inhabiting a particular ecosystem. Populations-all the individuals of a species living within the bounds of a specified area. Organs- a body part that is made up of multiple tissues and have a specific function in the body. Tissues: group of cells that work together performing a specialized function. Cells: life"s fundamental unit of structure and function. Organelles: various functional components present in cells. Molecules: chemical structure consisting of two or more units called atoms. Evolution- change in gene frequency in a population. Humans selectively breed and mate plants/animals with particular traits.
