Biology- the Science of Life
Name some ways that Biology is relevant to
society today.
What is living and what is not?
•Organisms are composed of cells
•Organisms grow and develop
What is living and what is not?
•Organisms regulate their metabolic processes
•Movement is a basic property of cells
What is living and what is not?
•Organisms respond to stimuli
•Organisms reproduce
•Populations evolve and become adapted to the environment
Genes
Proteins
Hormones
Neurotransmitters
Hierarchical
Reductionism
Levels of Organization
Chemical level- atoms and molecules
Cellular level- prokaryotic and eukaryotic
Levels of Organization
Tissues- organization of cells
Organs- organization of tissues
Levels of Organization
Organ Systems- organization of organs
Organism- organization of organ systems
Populations Biosphere
Community Ecology
Ecosystem
Systematics- studies the diversity of organisms and their evolutionary relationships
Taxonomy- the science of naming and classifying organisms
Taxonomy is hierarchical
Kingdoms are broken down into phyla, class, orders, families, genera, and species
Archaea
Eubacteria
Eukarya
Two domains are dedicated to prokaryotes (organisms whose cells lack nuclei and other membrane-bound organelles)
Archaea
Eubacteria
One domain is dedicated to eukaryotes (organisms whose cells have nuclei and other membrane-bound organelles)
Eukarya
Eubacteria Fungi
Archaea Plantae
Protista Animalia
Eubacteria consists of bacteria
Archaea- unique group of prokaryotic organisms that have been split off from the bacterial kingdom
Protista- protozoans and algae
Developed the binomial nomenclature used today to classify organisms
