Characteristics of Life and CER
List the 8 characteristics of Life
- All Living things are made of cells
- All Living things reproduce
- All Living things obtain and use energy
- All Living things maintain homeostasis
- All organisms pass along hereditary traits
- All Living things respond to their environment
- All Living things grow and develop
- All Living things adapt to their environment through evolution
Unicellular organism definition and examples
only one cell
examples: bacteria and protists
Cell definition
the smallest unit capable of all life functions
Multicellular organisms definition
made up of many cells and cells have specialized functions in the body
reproduction definition
the process of producing new organisms of the same type
asexual reproduction
a single parent organism makes a copy of itself
sexual reproduction
two different parent organisms contribute genetic information via sex cells
two types of organisms
unicellular and multicellular
two types of reproduction
sexual and asexual
two parts of metabolism
catabolism and anabolism
catabolism definition
the breakdown of food components into smaller , simpler particles
anabolism definition
when the the body “burns” carbohydrates and energy to give us usable energy
metabolism definition
the process of our bodies transforming food into usable energy
what is the process of transforming food into energy called
metabolism
homeostasis definition
a stable state of conditions in the body that are nessesry for life
examples of homeostasis
body temp, blood volume, ph balance, water balance and volume
what do chromosomes containing genes carry
hereditary information
genes are composed of what
DNA
examples of stimuli
light, temp, odor, sound, gravity, heat, water, pressure
growth definition
increase in mass and size of an organism, for multicellular organisms, that includes creating more cells
growth in a multicellular organism
increase in number of cells
development defingition
a change is he physiological and functional maturation of an organism over their lifetime
different between growth and development
growth - physical growth with more cells
development - maturation
adaptation descrition
enables organisms to become better suited to their environment over a long period of time
what does CER stand for
claim, evidence, reasoing
claim definition
an accurate, specific, one sentence statement that answers your research question with zero evidence
evidnence definition
scienctifiv data (qualitative or quantitative) that supports your claim, should have many pieces of evidencere
reasoning definition
explains why the data you chose counts as evidence and connects each pieve of evidence to your claim
when to use a CER
use it to engage in a structured argumentation to explain a scientific concept
use it after an experiment to explain why a hypothesis was supported or refuted
use it to discuss claims
a hypothesis can be…
supported or refuted
