bio 1.1-1.4

first characteristic of life

made of cells (prokaryotic and eukaryotic)

second characteristic of life

respond to stimuli (external and internal)

third characteristic of life

maintain homeostasis

fourth characteristic

acquire energy (autotrophic - makes own food & heterotrophic - gets carbon & energy from its food sources)

cellular respiration

C6H12O6 + 6O2 -> 6CO2 6H2O + ATP

photosynthesis

sunlight + 6H2O + 6CO2 -> C6H12O6 + 6O2

fifth characteristic of life

grow and develop (cell division - makes more cells)

sixth characteristic of life

reproduce themselves (asexual - single organism produces offspring : sexual - genetic material from 2 parents is combined creating genetic diversity)

seventh characteristic of life

contain DNA (the code/instruction for life)

eighth characteristic of life

have the capacity to evolve

types of living things (6 kingdoms)

eubacteria, archaebacteria, protista, fungi, plantae, animalia

subatomic particles

the particles that make up an atom (first hierarchy of life)

atom

an element (second hierarchy of life)

molecule

atoms bonded together (third hierarchy of life)

organelle

a structure within a cell that performs a special function (fourth hierarchy of life)

cell

smallest unit of life (fifth hierarchy of life)

cell specialization

cells come in different structures that correspond with their functions

tissue

a group of cells that perform a specific function (sixth hierarchy of life)

organ

a structure usually composed of several tissue types that form a functional unit (seventh hierarchy of life)

organ system

two or more organs working together in the execution of a specific bodily function (eighth hierarchy of life)

multicellular organisms

a living thing composed of many cells, many organ systems working together (ninth hierarchy of life)

population

members of one species inhabiting the same area (tenth hierarchy of life)

community

2 or more populations or different species living & interacting in the same area (all biotic - eleventh hierarchy of life)

ecosystem

a community together with its nonliving surroundings (abiotic & biotic - twelfth hierarchy of life)

our biome

deciduous forest

biosphere

all earth’s ecosystems combined, they are areas that are inhabited by life (thirteenth hierarchy of life)

taxonomy

the system scientists use to classify organisms and to assign each with a scientific name

taxons

domain, kingdom, phylum, class, order, family, genus, species

binomial nomenclature

Genus species

abiogenesis

theory of how life on earth arose from non-living matter

anearobic

no oxygen on earth (living or functioning without oxygen)

aerobic

oxygen on earth (living or functioning with oxygen)
