Plant and animals are dependent upon each
other for life and recycle energy products.
Plants obtain energy through the process of photosynthesis

Occurs in the chloroplast, chlorophyll (pigment) traps sunlight

CO2 is used to make sugars that will be used to make cellulose for cell walls

Sunlight + H2O + CO2 => C6H12O6 + O2
Animals obtain energy through the process of cellular respiration.

Occurs in the mitochondria.

Sugars in food are broken down to make Adenosine Tri-Phosphate (ATP)

ATP is stored energy, ADP is released energy. ATP and ADP are cycled by
plants and animals

C6H12O6 + O2 => ATP + H20 + CO2
There are six kingdoms of life:

Archebacteria- prokaryote, live in oxygen-free environments

Eubacteria- prokaryotes, auto-/heterotrophic, some cause disease

Protista- uni-/multicellular, eukaryote, heterotrophic, some are parasitic

Fungi-multicellular, eukaryote, heterotrophic, decomposers

Plant-multicellular, eukaryote, autotrophic

Animal-multicellular, eukaryote, heterotrophic

Viruses are not considered living because they need a host.
Taxonomy is the classification of living
things based on similar characteristics.
 The taxa groups are kingdom, phylum, class, order,
family, genus and species.
 The more taxa organisms share in common, the more
similar they are
 Additional kingdoms were realized with the discovery of
the microscope
 Binominal nomenclature is the process of naming
organisms developed by Linnaeus
 Scientific names are written in Latin and include the
Genus name followed by the species name
 Body structures, behaviors, and DNA can be used to
compare relationships between organisms
